Adds a new HiLo alarm trigger type with four configurable setpoints
(LoLo / Lo / Hi / HiHi). Each setpoint carries an optional priority,
deadband (for hysteresis), and operator message. The site runtime emits
AlarmStateChanged with an AlarmLevel field so consumers can differentiate
warning vs critical bands.
Plumbing:
- new AlarmLevel enum + AlarmStateChanged.Level/Message init properties
- AlarmTriggerEditor (Blazor) gets a HiLo render with severity tinting
- AlarmTriggerConfigCodec extracted from the editor for testability
- sitestream.proto carries level + message over gRPC
- SemanticValidator enforces numeric attribute, setpoint ordering,
non-negative deadband
- on-trigger scripts get an Alarm global (Name/Level/Priority/Message)
so notification routing can branch by severity
- per-instance InstanceAlarmOverride entity + EF migration + flattening
step + CLI commands; HiLo overrides merge setpoint-by-setpoint, binary
types whole-replace
- DebugView shows a Level badge + per-band message tooltip
- App.razor auto-reloads on permanent Blazor circuit failure
- docker/regen-proto.sh automates the proto regen workflow (the linux/arm64
protoc segfault means generated files are checked in for now)
Replace raw-JSON text inputs with rich UI: script parameter/return types use
a JSON Schema builder (SchemaBuilder + JsonSchemaShapeParser, with a migration
to convert existing definitions); alarm trigger config uses a type-aware
editor with a flattened attribute picker (AlarmTriggerEditor). AlarmActor
gains optional direction (rising/falling/either) on RateOfChange triggers.
Composition leaves were rendered flat — the cascaded inner derived
templates existed in the DB but the tree only showed the outer slot
name (e.g. "Tank Monitor > DrivePump") with no way to see DrivePump's
own TempSensor + AlarmSensor slots.
BuildCompositionLeaves now recurses: for each composition under a
template, look up the composed template (which after derive-on-compose
is a derived row carrying its own Compositions) and build its slot
leaves as children. HasChildrenSelector loses the
"not a composition" guard so nested leaves render with the expand
chevron.
The right-click context menu is now the single entry point for every
per-row action — folders, templates, and composition leaves. Drop the
⋮ kebab buttons that duplicated the menu and the click-to-open
behavior that was easy to trigger by accident while navigating the
tree. Templates and composition slots open on double-click instead.
- RenderNodeKebab removed entirely.
- Selectable / SelectedKeyChanged / OnTreeNodeSelected dropped from
the TreeView wiring — single-click no longer navigates.
- New OpenTemplate(id) helper bound to @ondblclick on Template and
Composition labels.
Derived templates are slot-owned and reached only via their owning
parent's composition leaf in the tree — there's no scenario where
listing them as standalone root nodes is useful, so the toggle was
dead UI. Remove the form-switch, the _showDerived state, and the
OnToggleShowDerived handler; BuildTemplateTree filters derived
templates out unconditionally.
Move composition CRUD off the TemplateEdit page and onto the tree
context menu, matching Aveva's Template Toolbox flow.
- New ComposeIntoDialog: pick a parent template, slot name (defaults
to the source template's name).
- "Compose into…" on every base template's context menu (kebab + right
click) opens the dialog and calls AddCompositionAsync.
- "Rename…" on composition leaves opens a prompt and calls
TemplateService.RenameCompositionAsync. The owning composition row
AND its owned derived template are renamed atomically; duplicate
slot names or derived-name collisions abort with a clear error.
- "Delete" on composition leaves confirms + cascade-deletes the
composition (and its derived template via DeleteCompositionAsync).
- "New Derived Template" menu item renamed to "New Inheriting Template"
to disambiguate from the new derive-on-compose meaning.
TemplateEdit's Compositions tab, Add Composition form, and
Add/DeleteComposition handlers + state fields are deleted — the tree
is now the single source of truth.
Derive-on-compose guarantees at most one slot owner per template, so the
Parent.* context in the Monaco editor resolves directly via
OwnerCompositionId without a picker. Base templates suppress Parent.*
assistance entirely (empty context).
Removed the multi-parent <select> dropdown from the Add Script form and
the now-redundant _selectedParentIndex / OnParentContextChanged plumbing.
ActiveEditorParent collapses to _editorParents.FirstOrDefault().
Templates tree hides IsDerived templates by default. A "Show derived"
form-switch in the page header toggles them into the listing so users
can reach orphaned derived templates when they need to.
TemplateEdit:
- Banner on derived templates: links to the base + the composing owner /
slot name pulled from OwnerCompositionId.
- Attributes/Scripts tables grew a context-aware column:
* On derived templates: a Source badge (Inherited / Override / Local)
plus a 🔒 Base-locked badge when the base marks LockedInDerived.
* On base templates: a switch that flips LockedInDerived through
UpdateAttribute/UpdateScript.
- Effective Value / Code now resolves from the base when an inherited row
carries a stale snapshot — matches the flatten-time behavior so the UI
doesn't lie.
- Override / Revert-to-base actions added to the row kebab; delete is
hidden on inherited rows (the base owns those).
Two caveats from the script-scope rollout addressed:
1. ITemplateEngineRepository.GetTemplatesComposingAsync — a scoped
query that returns only the templates referencing a given template
via Compositions, eager-loaded with their Attributes / Scripts /
Compositions. Replaces the GetAllTemplatesAsync + filter pattern
in TemplateEdit so the Monaco metadata fetch doesn't pull the
entire template catalog to find one parent.
2. Multi-parent picker. The previous implementation suppressed Parent
assistance entirely when more than one template composes the open
one. Now TemplateEdit collects every parent into _editorParents
and renders a small `select` above the script editor when there
are >1, letting the user choose which parent's metadata drives
Parent.Attributes / Parent.CallScript completion + diagnostics.
Single-parent templates skip the picker (no UI change). Zero
parents (root template) hide the picker and surface no Parent
assistance.
Browser-verified on the Sensor Module template (composed by both Pump
and Variable Speed Motor): picker shows both options, switching
updates the editor's parent metadata immediately via the existing
GetContext callback.
Test counts unchanged (159 / 199); the new repo method is exercised
end-to-end by the parent-picker browser path.
Phases 3+4 of the script-scope rollout. Wires the runtime accessors
landed in efba01d through to Monaco completion, diagnostics, and
hover.
New analyzer surface in ScriptAnalysisService:
String-literal completion contexts (added to TryStringLiteralCompletions):
Attributes["..."] -> SelfAttributes
Children["..."] -> composition names
Children["X"].Attributes["..."] -> child template's attributes
Children["X"].CallScript("...") -> child template's scripts
Parent.Attributes["..."] -> parent template's attributes
Parent.CallScript("...") -> parent template's scripts
Diagnostics:
SCADA006 Attribute "Typo" is not declared on {this template,
child composition 'X', the parent}. (warning)
SCADA007 Composition "Unknown" is not declared on this template.
(warning)
CallShared / CallScript snippet-expansion now routes through the
child / parent shape catalogs when invoked on Children["X"] /
Parent — picking a child script accepts `Sample", ${1:count})`.
Contract additions:
- AttributeShape (Name, Type) record
- CompositionContext (Name, Attributes, Scripts) record
- SelfAttributes / Children / Parent fields on DiagnoseRequest,
CompletionsRequest, HoverRequest, SignatureHelpRequest
ScriptHost (analyzer-side globals) gains stub AttributeBag /
ChildrenBag / CompositionBag types so Roslyn doesn't emit CS0103 on
Attributes / Children / Parent. The stubs are never invoked — only
their signatures are read by the analyzer's compilation pass.
MonacoEditor.razor exposes SelfAttributes / Children / Parent
parameters; GetContext returns them; monaco-init.js forwards all
three on completion / hover / signature-help / diagnostics requests.
TemplateEdit fetches each composition's resolved child template
shape via GetTemplateWithChildrenAsync, and queries GetAllTemplatesAsync
for any single parent that composes the open template. Multi-parent
or no-parent → Parent is suppressed.
11 new xUnit tests on the new completion / diagnostic paths. Total:
149 -> 159.
Browser-verified via curl:
- Children["..."] suggests composition names
- Attributes["..."] suggests attributes with type detail
- Attributes["Typo"] squiggles SCADA006
- Children["Unknown"] squiggles SCADA007
- No spurious CS0103 on the new accessors
Hover, signature help, and inlay hints for the new accessors keep
working because they reuse the same dispatch logic.
Three more editor features rolled in:
1. Roslyn Format command.
New POST /api/script-analysis/format runs Formatter.Format() from
Microsoft.CodeAnalysis.CSharp.Workspaces on the parsed script
tree. monaco-init.js registers a DocumentFormattingEditProvider
so Ctrl/Cmd-Shift-F and the toolbar "Format" button both work.
2. Inlay hints with parameter names.
New POST /api/script-analysis/inlay-hints walks CallShared /
CallScript invocations and emits InlayHint records positioned at
each argument with the matching parameter's name (e.g. "name:").
Ghost text appears via Monaco's InlayHintsProvider.
3. SCADA005 argument-type diagnostic.
Literal type vs. declared parameter type check on every
CallShared/CallScript argument. Float accepts Integer literals;
Object/List accept anything; null only matches reference-ish
types. Legacy lowercase types ("string" etc) from the DB are
normalized to the canonical set before comparison so existing
data doesn't false-negative. Non-literal args (variables,
expressions) are skipped — out of scope for a cheap pass.
4. Parameters["name"] hover.
Hover endpoint now also resolves Parameters["X"] element-access
keys against the form's DeclaredParameterShapes and returns
"parameter `name: String`"-style markdown. MonacoEditor surfaces
the new DeclaredParameterShapes parameter; ScriptParameterNames
gets a ParseShapes companion.
5. Problems panel.
Bootstrap card under the editor listing every marker with
severity badge, line number, message, and SCADA / CS code. Click
a row to scroll the editor to that line and focus. JS now
invokes OnMarkersChanged on the .NET side whenever
setModelMarkers fires, so the panel stays in sync with the
editor.
6. Editor toolbar.
Small top-right strip on each editor with Format / Wrap /
Minimap / Theme toggles. New MonacoBlazor.format,
setEditorOption, and revealLine JS APIs back the buttons and the
problems-panel scroll-to-line.
Contracts:
- FormatRequest / FormatResponse
- InlayHintsRequest / InlayHintsResponse / InlayHint
- HoverRequest.DeclaredParameters
- MonacoEditor.DeclaredParameterShapes parameter
- MonacoEditor.MarkersChanged callback
- ScadaContext.DeclaredParameterShapes
10 new xUnit tests covering format, inlay hints, SCADA005 (string-
expects-integer, integer-expects-string, float-accepts-integer,
object-accepts-anything, non-literal-skipped), and Parameters key
hover. Total: 139 -> 149.
Microsoft.CodeAnalysis.CSharp.Workspaces 4.13.0 added to pull in
Formatter and AdhocWorkspace.
Browser-verified: typing `CallShared("Greet", 42)` now shows the
"name:" inlay hint and a SCADA005 squiggle on `42`; Parameters["typo"]
shows SCADA003 as before; the toolbar buttons all work.
Now that the form holds parameter + return shapes for declared
parameters, sibling scripts (template Scripts tab), and shared
scripts (via SharedScriptCatalog), the editor leverages them four
ways:
1. Snippet expansion on accept.
Picking a CallShared or CallScript completion inserts the full
call template with tabstops, e.g. `Greet", ${1:name})`. The JS
provider extends the completion range over Monaco's auto-closed
`")` so the snippet replaces the closing pair cleanly. Items
carry insertTextRules=4 (InsertAsSnippet) and a command to
immediately trigger parameter hints after acceptance.
2. Hover info.
Hovering the script name token inside CallShared("X") or
CallScript("Y") shows a markdown tooltip with the call signature
and return type. New endpoint POST /api/script-analysis/hover.
3. Signature help.
Inside CallShared(...) / CallScript(...) Monaco shows the
parameter strip with the active parameter highlighted. The
service walks up from the cursor to the nearest enclosing
InvocationExpression and resolves which argument index the
cursor is on. New endpoint POST /api/script-analysis/signature-help.
4. Argument-count diagnostic (SCADA004) and unknown-Parameters-key
diagnostic (SCADA003). The Diagnose pipeline now consults the
declared parameters and sibling/shared shapes to flag:
- Parameters["typo"] when "typo" isn't on the form (warn)
- CallScript("Calc", 1) when Calc declares 2 required args (err)
- CallShared("Greet", 1, 2, 3) when Greet declares 1 arg (err)
Optional parameters relax the required-count bound.
Contract changes:
- ScriptShape / ParameterShape records
- ISharedScriptCatalog.GetShapesAsync (replaces GetNamesAsync)
- new HoverRequest/Response, SignatureHelpRequest/Response
- CompletionsRequest.SiblingScripts: string[] -> ScriptShape[]
- DiagnoseRequest gains DeclaredParameters + SiblingScripts
- CompletionItem gains InsertTextRules (Monaco snippet rule)
Form wiring:
- TemplateEdit passes ScriptShapeParser.Parse(...) per sibling
- MonacoEditor surfaces SiblingScripts: IReadOnlyList<ScriptShape>
- GetContext returns shapes to JS on each completion/hover/sig
request
10 new ScriptAnalysisServiceTests covering all four features plus
optional-parameter edge cases. Existing tests updated for the
contract changes. Total: 113 -> 139.
Browser-verified via direct curl + Monaco marker readback:
- SCADA003 squiggle on Parameters["typo"]
- Snippet item Greet", ${1:name}) with insertTextRules=4
- Hover markdown shape signature
- Signature help parameter strip
Wave 3 of the Monaco/Roslyn integration. Adds the four extensions
agreed in the design Q&A:
1. Parameters["..."] keys — when the cursor is inside a string
literal that's the index of a Parameters[] element-access,
completions return the parameter names declared in the form's
ParameterListEditor.
2. CallShared("...") names — when the cursor is inside a string
literal argument to a CallShared(...) invocation, completions
return the names of all shared scripts (resolved server-side
via SharedScriptService).
3. CallScript("...") names — same shape, but uses sibling-script
names passed from the form (TemplateEdit's _scripts list).
4. Forbidden-API diagnostic — squiggles uses of the documented
script trust model bans: System.IO / Diagnostics / Reflection /
Net / Threading.Thread namespaces, plus the named types File,
Directory, Process, Thread, Socket, etc. New diagnostic codes
SCADA001 (using directive) and SCADA002 (type identifier).
ScriptAnalysisService gains a SharedScriptService dependency
(scoped, hence the analyzer is now scoped too); CompletionsRequest
carries DeclaredParameters and SiblingScripts; Complete is now async.
MonacoEditor.razor exposes DeclaredParameters / SiblingScripts
parameters plus a [JSInvokable] GetContext() so the JS side asks
for the latest form state on every completion request. The
provider in monaco-init.js looks up the owning editor from the
internal editors map and forwards the context.
ScriptParameterNames helper parses the ParameterListEditor JSON
into a name list — used by SharedScriptForm, ApiMethodForm, and
TemplateEdit's Add-Script form to populate the Monaco context.
Smoke-verified via direct fetch + Monaco trigger:
- var x = Parameters[" → popup: "name" (declared parameter)
- var y = CallShared(" → popup: GetWeather, Greet
- using System.IO; → SCADA001 squiggle
- Process.Start(...) → SCADA002 squiggle
- File.ReadAllText(...) → SCADA002 squiggle
Also fixed: ScriptAnalysisService scoped (was singleton, broke DI
because SharedScriptService is scoped); JS normalizes Pascal-case
context keys from Blazor's record serialization to camel-case for
the request body.
Vendors Monaco 0.55.1 min/vs/ (~15 MB) at
wwwroot/lib/monaco/vs/. No CDN dependency; works on air-gapped
deployments. Loaded lazily on first script-edit via the AMD loader.
wwwroot/js/monaco-init.js exposes window.MonacoBlazor with
createEditor / setValue / getValue / setMarkers / dispose. Handles
loader bootstrap, DotNet round-trip on content change, and marker
sets for later diagnostic wiring.
Components/Shared/MonacoEditor.razor is a Blazor wrapper with
Value / ValueChanged / Language / Height / ReadOnly parameters and
IAsyncDisposable teardown. Bidirectional binding tracks
_lastSentValue to avoid push/pull loops.
Replaces the plain textareas in SharedScriptForm, TemplateEdit's
Add-Script form, and ApiMethodForm. Default height 320px ≈ the
previous rows=10. Build / tests / dialog flow unaffected.
Wave 1 of three. Roslyn-backed completions and SCADA-specific
extensions follow in subsequent commits.
Two new shared components in Components/Shared:
- ParameterListEditor: table of rows (name + type + item type + required + remove)
- ReturnTypeEditor: single type (+ item type when List)
Both round-trip the same JSON shape already stored on the entity:
parameters: [{"name":"x","type":"String","required":true},...]
return: {"type":"List","itemType":"Integer"} | null
Type set follows the Inbound API validator (Boolean, Integer, Float,
String, Object, List). Legacy values normalize on read — Int32 / int64
/ Double / Decimal / lowercase string / etc all coalesce to the new
set so existing rows render correctly. Re-saving persists the
normalized form.
Applied to:
- SharedScriptForm
- TemplateEdit Add Script form (also surfaces ParameterDefinitions
+ ReturnDefinition which the entity supported but the form was
never wiring through)
- ApiMethodForm
Graceful degradation: invalid JSON is shown with a "Start fresh"
escape hatch instead of crashing the form.
Eliminates the per-page <ConfirmDialog @ref="_confirmDialog"
ConfirmButtonClass="btn-danger" /> boilerplate. Pages now inject
IDialogService and call ConfirmAsync(title, message, danger: true)
programmatically.
New scoped service holds a single active dialog (throws on nested
calls), with a global DialogHost mounted once in MainLayout that
renders the modal markup, owns body scroll-lock via Bootstrap's
modal-open class, traps focus on the modal element, and handles
Escape-to-cancel.
Same service also exposes PromptAsync, used to replace the bespoke
NewFolderDialog. Both ConfirmDialog and NewFolderDialog components
are deleted — their callers (~13 pages across Admin/Design/Deployment
/Monitoring) now go through the service.
DiffDialog stays as-is — different use case (before/after content).
bUnit tests in TopologyPageTests, DataConnectionsPageTests, and
TemplatesPageTests register IDialogService in their service
collection.
Also: a top-of-file Razor comment on Sites.razor pointing future
implementers at it as the reference list-page pattern.
Dashboard: user-info card demoted; 4 KPI cards (Sites, Data
connections, Templates, API keys) sourced from existing repositories;
3 Quick-action link cards (Health, Audit Log, Templates). Inline
max-width style replaced with Bootstrap utilities.
Health: KPI row condensed to Online / Offline / Sites with active
errors (Total Sites and Total Script Errors dropped). Per-site cards
re-laid out 2-column with each subsection (Data Connections,
Instances & Queues, Errors & Parked Messages) inside Bootstrap
collapse panels collapsed by default. Online / Offline / Primary /
Standby badges paired with shape glyphs (o / * / triangle) plus
aria-label.
EventLogs: filter row wrapped in a Bootstrap collapse toggled by
"Filter options (n active)"; per-row View toggle reveals the full
message in a collapse row; "Keyword" relabeled "Message contains";
all filter inputs gain id+label-for+aria-label; severity badges paired
with a leading glyph; explicit "End of results" terminator on
Load more.
ParkedMessages: Message ID rendered as <code>{first 12}...</code>
plus a clipboard button; per-row View toggle reveals full error;
action buttons get aria-label="{Retry|Discard} message {id}";
in-flight spinner inside the active button.
AuditLog: pagination Next-disabled now uses
_page * _pageSize >= _totalCount via HasMore helper (fixes the
exactly-page-size edge case). Clear filters button added. Entity ID
rendered as code + clipboard button. View/Hide buttons gain
aria-label referencing the entry id. State JSON larger than 1 KB
renders a "View in modal" button instead of the inline overflow.
New shared DiffDialog mirroring ConfirmDialog's API
(ShowAsync(title, before, after)) so live-data pages stop
hand-rolling Bootstrap modal markup.
Topology: <h4> in flex header, aria-labels on Expand/Collapse/Refresh
and the inline rename input, Live-updates toggle (suppresses the 15s
timer when off), instance/area counts moved into a summary alert
above the tree, Stale badge paired with bi-exclamation-triangle icon
+ aria-label, hand-rolled Diff modal replaced with <DiffDialog @ref>.
Deployments: pause/resume auto-refresh button replaces the static
"Auto-refresh: 10s" text; summary cards switch to
col-lg-3 col-md-6 col-12; InProgress spinner gets role="status" +
aria-label; failed rows pick up a bi-x-circle icon next to the
Status badge; Deployment ID + Revision folded into one
{id}@{revision[..8]} cell; inline Error column collapses behind a
per-row "View error" toggle; bare empty-state text upgraded to the
centered muted block.
DebugView: status-strip card at the top showing instance / connection
state / last snapshot timestamp plus a "Start fresh" button when the
page auto-reconnected from localStorage. Per-table filter input,
scroll-lock toggle, Clear button, and a 200-row queue-style cap.
<tbody> elements gain aria-live="polite" aria-atomic="false" for
screen-reader announcements. Quality and Alarm-State badges get
aria-labels; timestamps display HH:mm:ss with full ms in a hover
tooltip. Auto-reconnect surfaces a toast with autoDismissMs: 8000.
Templates: <h4> in flex header, Expand/Collapse moved into a Bulk
actions dropdown, hover-visible kebab on tree nodes with aria-labels.
TreeView CSS gets a .tv-kebab opacity-on-hover utility.
TemplateCreate: form-control (not -sm) for primary inputs; accessible
Back button.
TemplateEdit: Properties card vertical-stacked with Save at the
bottom-right and Parent rendered as readonly plaintext. Add-member
forms (Attributes, Alarms, Scripts, Compositions) reflowed from
horizontal row g-2 align-items-end into cards with stacked col-12
inputs (Scripts gets rows=10). Lock/Unlock badges show full words.
Per-row Delete moved into a kebab dropdown. Tab nav gains
role="tablist" / role="tab" / aria-selected / aria-controls and panels
get role="tabpanel". Validation entries get consistent strong-and-
muted styling.
SharedScripts: migrated from table to card grid (col-lg-6) matching
Sites; cards show code preview + param/return badges + Edit + kebab.
Search filter, empty state CTA, @key.
SharedScriptForm: small ?-icon tooltips next to Parameters and Return
Definition labels.
ExternalSystems: SMTP split out to its own page; remaining tabs (
External Systems, DB Connections, Notification Lists, API Methods,
API Keys) unified as card grids with per-tab search + empty-state CTA.
Tab nav gets full ARIA instrumentation. Header gains a link to the
new SMTP page.
New page SmtpConfiguration.razor at /design/smtp: vertical-stacked
form using the existing Credentials field on the entity.
ExternalSystemForm: AuthConfig placeholder updates based on the
selected AuthType (None / ApiKey / BasicAuth).
DbConnectionForm: form-text below Connection String noting that the
value is stored in plain text and is admin-only.
ApiMethodForm: Script textarea rows=10; JSON example placeholders
for Params and Returns.
NotificationListForm: form-control sizing on Name/email inputs;
thead.table-dark -> table-light on the recipients table.
LdapMappings: flex header, search filter, per-row Edit + kebab Delete,
@key, dropped Site-Scope-Rules cell in favor of a {n rule(s)} badge.
LdapMappingForm: two stacked cards (Mapping then Site Scope Rules);
scope rules render as removable chips with an inline "Add scope rule"
form; create-mode disables the scope card with an explainer; role
select gets form-text help.
DataConnections: <h4> in flex header, Bulk actions dropdown holding
Expand/Collapse, hover-visible kebab on tree nodes mirroring the
right-click context menu, aria-labels, "No connections match the
filter." inline empty state.
DataConnectionForm: Site rendered as readonly plaintext + lock-after-
creation note in edit mode; parallel Primary endpoint / Backup endpoint
headings; "Optional" badge on Backup when null; form-text on
FailoverRetryCount.
ApiKeys: search filter, Status column dropped (state now lives in the
kebab menu label "Disable"/"Enable"), Edit + kebab actions, @key,
aria-labels.
ApiKeyForm: nested card removed; fixed-text Back header; real
clipboard copy via IJSRuntime + toast confirmation.
Test selector fix in DataConnectionFormTests for the new Site
readonly-plaintext rendering.
ConfirmDialog locks body scroll via IJSRuntime + Bootstrap's
modal-open class on show, restores on hide. Escape key now closes
the dialog; default ConfirmButtonClass flipped from btn-danger to
btn-primary so non-destructive confirms aren't red. Destructive
callsites (Delete, Discard) get explicit ConfirmButtonClass="btn-danger".
ToastNotification adds aria-live="polite" + aria-atomic="true" on the
container and an optional autoDismissMs parameter on every Show* method.
LoadingSpinner text-muted -> text-secondary for contrast.
DataTable gains a clear (x) button on the search input and applies
disabled / aria-disabled directly to the pagination buttons.
NewFolderDialog splits backdrop and modal markup to match ConfirmDialog.
NavMenu wraps the nav list in an overflow-y scroll container so the
username/sign-out footer stays anchored, and section headers convert
from <li> to <div role="presentation">.
MainLayout adds a hamburger toggle for <lg viewports; sidebar collapses
via Bootstrap collapse data attributes.
App.razor extracts inline <style> block to a shared site.css; adds a
left-border accent on the active nav link; switches the reconnect
modal to modal-dialog-centered.
Login uses d-flex / min-vh-100 centering. NotAuthorizedView gets the
same centered layout plus the ScadaLink brand heading.
Sites.razor: only the new ConfirmButtonClass="btn-danger" follow-up.
The dense table buried high-signal fields (name, identifier, connections)
under four 80-character Akka/gRPC URLs truncated mid-string. Replace with
a 2-column responsive card grid; cluster-node addresses now live in a
collapsed disclosure with copy-to-clipboard. Adds client-side filter,
empty/no-match states, kebab menu for less-frequent actions, and
@key=site.Id to keep Bootstrap collapse state from leaking across cards
when the filter changes.
Brings the Data Connections admin page up to the same UX standard as the
Topology page:
- Search box with dim non-matches (opacity 0.4, shape preserved)
- Toolbar: + Connection (disabled until a site is selected), Refresh,
Expand, Collapse
- Site context menu gains "Add Connection here" that navigates with
?siteId= so the form preselects + locks the Site field
- Form gains "Primary Endpoint" / "Backup Endpoint" h6 subsection
headers matching the SiteForm convention; Failover Retry Count moved
inside the Backup subsection
- URL renamed: /admin/connections (primary) + /admin/data-connections
(legacy secondary @page). Same dual-route treatment on the form
- Nav label: "Data Connections" -> "Connections"
- Adds DataConnectionsPageTests bUnit suite (6 tests)
Single /deployment/topology page replaces /deployment/instances (legacy URL
preserved as a secondary @page directive) and the /admin/areas* CRUD pages.
TreeView with Site → Area → Instance, V1–V7 visual guide (bi-building /
bi-diagram-3 / bi-box), always-visible empty containers, search dim, F2
inline area rename, and right-click context menus per node kind (Add Area,
Move to Area…, lifecycle actions, etc.).
Adds AreaService.MoveAreaAsync with cycle prevention, same-site enforcement,
and name-collision check at the new parent. Instance rename intentionally
out of scope — UniqueName is the site-side actor identity, requires its own
design pass.
Right-click a template now offers "New Derived Template" — opens
TemplateCreate with the parent pre-selected via a new ?parentId query
parameter. Composition rows in the tree drop the trailing
"→ TargetName" muted text; the kind glyph plus the instance name carry
enough meaning, and the composed template is one click away from the
row's right-click menu.
Template inheritance is set once at create time and immutable on update.
UpdateTemplateAsync now returns "Parent template cannot be changed after
creation." when the caller sends a parent that differs from the stored
value — server-side enforcement covers UI, ManagementService, and CLI.
TemplateEdit renders the parent as static plaintext rather than an
editable dropdown; TemplateCreate's parent picker is unchanged.
Templates page is now a tree-only browser; editing happens on a dedicated
TemplateEdit page. Drag-drop is replaced by context-menu Move-to-Folder.
TreeView gains Bootstrap Icons (chevron + per-kind glyphs), ancestor guide
lines, defined hover/selected/focus tokens, and Escape-dismisses-menu per
the new Visual Design Guide (V1-V7) in Component-TreeView.md.
The previous fix tried to defer page-side RevealNode to the second
render so TreeView's async sessionStorage load could finish first. In
practice Blazor Server didn't always fire a second OnAfterRenderAsync
on the page after the deep-link load, so the reveal never ran.
Real fix: change TreeView's storage-load to UNION the restored keys
with whatever's already in _expandedKeys, instead of REPLACING. That
way the page can call RevealNode whenever it wants and the storage
restore can't clobber the reveal regardless of completion order. The
page-side guard simplifies back to a one-shot reveal on first render.
Semantic note: if a deep-link reveal expands an ancestor that the user
had previously collapsed, the deep link wins. Intentional — the URL
expresses the navigation intent.
Both page.OnAfterRenderAsync(firstRender=true) and
TreeView.OnAfterRenderAsync(firstRender=true) ran concurrently:
- Page called RevealNode → added ancestor keys to _expandedKeys
- TreeView awaited treeviewStorage.load → replaced _expandedKeys with
the persisted set (often empty if user collapsed before navigating)
Whichever JS interop completed second won. When TreeView won, the deep-link
reveal silently lost. Gate the reveal on firstRender==false so it runs
strictly after TreeView's restore is done.
Without stopPropagation, dropping a template onto a folder fires both
OnDrop(folder) and OnDropOnRoot via event bubbling. The two async handlers
race on the same scoped DbContext, which is not thread-safe — the second
throws ObjectDisposedException and tears down the Blazor circuit. Surfaced
during browser smoke testing via JS-dispatched DragEvent sequence.
Smoke testing revealed two issues introduced by the modal extraction commit:
1. ErrorMessage / InitialName / TemplateName parameters on the dialog
components were passed as bare strings (e.g. ErrorMessage="_newFolderError")
instead of dereferenced C# expressions (ErrorMessage="@_newFolderError").
Razor treats unquoted-but-not-@-prefixed values to string parameters as
string literals — so the error block rendered the literal field name in
red whenever the modal opened. Non-string parameters (int/IEnumerable)
were fine since Razor treats those as C# expressions by default.
2. The Templates header + 4-button toolbar shared one flex row, but at
col-md-4 / col-lg-3 width the buttons overflowed into the right-column
empty-state area. Stack title above a full-width btn-group instead.
LmxProxy is no longer needed. Moved the entire lmxproxy/ workspace, DCL
adapter files, and related docs to deprecated/. Removed LmxProxy registration
from DataConnectionFactory, project reference from DCL, protocol option from
UI, and cleaned up all requirement docs.
Add NodeStatus record, IClusterNodeProvider interface, and AkkaClusterNodeProvider
that queries Akka cluster membership for all site-role nodes. HealthReportSender
populates ClusterNodes before each report. UI shows a row per node with
hostname, Online/Offline badge, and Primary/Standby badge. Falls back to
single-node display if ClusterNodes is not populated.
New fields in SiteHealthReport: NodeHostname, DataConnectionEndpoints
(primary/secondary), DataConnectionTagQuality (good/bad/uncertain),
ParkedMessageCount. New collector methods to populate them.
Health dashboard redesigned to match mockup: Nodes | Data Connections
(with per-connection tag quality) | Instances + S&F Buffers | Error
Counts + Parked Messages. Site names resolved from repository.
Areas page now shows a single TreeView with sites as roots and areas as
children. Context menus: sites get "Add Area", areas get "Add Child Area",
"Edit Area", "Delete Area" — each navigating to a dedicated page.
The Delete Area page shows a TreeView of the area and all recursive children
with assigned instances. Deletion is blocked if any instances are assigned
to the area or its descendants.
