The active workbench section (which panel renders). Round-trips through the section query param.
Protected ReadonlycdrConversation lifecycle (see onChatConversationCreated) — without it the first send no-ops.
Protecteddestroy$Provider-scoped Predictive Studio engine. Resolved in loadSection via
PredictiveStudioEngine.GetProviderInstance so a multi-provider client (or an embedded
non-default provider) reads the right server's PS reference data. Bound into the hosted panel's
[engine] input once loading completes.
True until the engine resolves; gates the panel host so [engine] is never bound before it's ready.
Set when loadSection fails to resolve the engine. The section templates render a "couldn't load" banner with a Try-again button (retryLoad) instead of silently showing empty panels, so a failed load is honest rather than indistinguishable from a genuinely-empty studio.
ProtectednavigationTab ID for query param notification scoping. Set by resource wrappers that render child dashboards, so the child knows which tab it belongs to. If not set, falls back to Data.Configuration.tabId.
If specified, this provider will be used for communication and for all metadata purposes. By default, if not provided, the Metadata and RunView classes are used for this and the default GraphQLDataProvider is used which is connected to the same back-end MJAPI instance as the Metadata and RunView classes. If you want to have this component connect to a different MJAPI back-end, create an instance of a ProviderBase sub-class like GraphQLDataProvider/etc, and configure it as appropriate to connect to the MJAPI back-end you want to use, and then pass it in here.
Protected ReadonlySectionFont Awesome icon for the section (chrome + shell tab).
Protected ReadonlySectionStable section identifier for agent context + (subclass) titling.
Protected ReadonlySectionHuman-readable section label used in chrome + agent context.
ReadonlysectionsStaticɵdirStaticɵfacSection-specific subtitle for the interior header (so every section doesn't repeat one generic line).
Returns either the default Metadata provider or the one specified in the Provider property, if it was specified
Returns either the default RunQuery provider or the one specified in the Provider property, if it was specified
Returns either the default RunReport provider or the one specified in the Provider property, if it was specified
Returns either the default RunView provider or the one specified in the Provider property, if it was specified
Public door label for templates (the error banner title). Mirrors the protected SectionLabel.
ProtectedextraDeep agent context for the Studio door (build/run workbench counts + active section).
ProtectedGetRead current query params from tab configuration. Use in initDashboard() / ngOnInit() to get initial URL state.
Get this component's tab ID. Checks ParentTabId input first (set by resource wrappers for child dashboards), then falls back to Data.Configuration.tabId.
ProtectedloadResolve the provider-scoped engine, then notify the shell. Always calls NotifyLoadComplete — even on failure — so the loading screen can never hang on a direct-URL section load.
The Overview panel's in-app navigation: switch section in-place, or cross to the Models door.
ProtectedNotifyAsk the host shell to close/dismiss this resource (typically: close the tab). Called by subclasses that hosted a form that emitted a 'dismiss' navigation event — most often, a brand-new record where the user clicked Discard. The record was never saved, the form is empty, and leaving it open serves no purpose. The tab-container listens for this and closes the workspace tab.
ProtectedNotifyCall this to notify the tab system that the resource's display name has changed. The tab container will update the tab title and browser title accordingly.
ProtectedNotifyProtectedNotifyChat-area created its backing conversation on the first send — capture it + leave new-mode so the thread renders.
Chat-area delivered the seeded prompt — clear the buffer so a re-render doesn't resend it.
ProtectedOnReact to deep-link / back-forward section changes after the initial mount.
Open the docked co-pilot (clean chat) — used by the read-only OpenModelDevAgentCopilot agent tool.
ProtectedpublishReport the section's state to the AI agent (async chat + realtime co-agent share this snapshot). Subclasses may override extraAgentContext to add section-specific fields. No client tools are registered — Predictive Studio surfaces are read/navigate-only to the agent; model creation, training, and promotion run through PS's own dialogs and the Model Development Agent.
ProtectedRefreshMarks this component's view (and its ancestors) as needing change detection and schedules a tick — the reliable way for a resource component to re-render after updating state from async work (RunView/RunQuery continuations, timers, websocket pushes, RxJS subscriptions).
WHY THIS EXISTS: the Explorer shell hosts resource components dynamically — createComponent()
ApplicationRef.attachView() — because tab content mounts into Golden Layout / cached DOM
containers, not into an Angular template. Since Angular 18's change-detection scheduler
rework (Explorer is on Angular 21), ApplicationRef.tick() only refreshes attached views
that are FLAGGED dirty; a root-level attached view whose component mutates plain fields from
an async continuation is never flagged, so the view silently never re-renders — even though
the component uses default (non-OnPush) change detection (issue #3106).The framework calls this automatically from NotifyLoadStarted() / NotifyLoadComplete(), so the standard load lifecycle re-renders without any subclass action. Call it yourself after any LATER async state change that must reach the DOM outside those signals.
Protectedregister🔒 Read/navigate-only agent tools for the Studio door: switch the active section, or open the docked Model Dev Agent co-pilot. NO build/train/publish tool is exposed — model creation runs through the co-pilot conversation (the approve-gated builder), never a fire-and-forget agent tool.
ProtectedResourceRetry the engine load after a failure — bound to the error banner's "Try again" button.
ProtectedUpdatePush query param changes to the URL. Creates a browser history entry. Safe to call during OnQueryParamsChanged — auto-suppressed to prevent loops.
Studio — the analyst workbench door (one of Predictive Studio's three consolidated nav items, alongside
PredictionsandModels). Hosts the build/run section panels (ps-home,ps-pipelines,ps-catalog,ps-experiments,ps-compare) behind an internal left-nav grouped by lifecycle (Overview · Build · Run), so the outer app nav stays quiet while analysts get all the depth one click in. The active section round-trips through thesectionquery param (deep links + back/forward). A single docked Model Development Agent copilot is shared by every section's "Ask the agent" CTA — wired with the full conversation lifecycle (isNewConversation→conversationCreated) so the first message actually creates + sends. Cross-door navigation (to a Models section) routes via the nav service; see routeHomeNavigate.
