Protecteddestroy$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.
StaticɵdirStaticɵfacFiltered list of existing lists eligible as compose targets. We exclude lists already in the selected operands (committing to a source list would be a self-referential compose) and lists from other entities (the entity invariant still applies).
Display name of the entity currently locking the picker — drives the "Comparing operands of type: …" hint in the UI. Falls back to the first available denormalized name we have.
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 RunView provider or the one specified in the Provider property, if it was specified
Combined operand count — drives "≥ 2 operands" checks for showing operation buttons + the Venn diagram empty-state.
Cancel the add to list dialog
Clear all selections and reset state
Commit the compose: either materialize a new list (client-side using the previewed record IDs) or merge into an existing list via the server's ComposeLists + ApplyListDelta flow.
Confirm adding records to selected list
Run the export with the user's selected format + columns. Bulk-load via RunView restricted to the chosen Fields so we don't shuttle data we'll then throw away.
Filter available lists for add-to-list dialog
Same logic as filterAvailableLists for the view picker. Views are
locked to the same entity as any already-selected list or view.
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.
True when this resource holds in-progress user edits that a silent replacement would destroy. Consulted by the shell before consuming a temporary record tab under the preview-tab model (see TabRequest.TempScope): an editing tab is never replaced — the next open lands in its own tab instead, so the edit survives.
Default false: most resources are read-only surfaces with nothing to lose. Resources that host an editable form override it.
A callback method that performs custom clean-up, invoked immediately before a directive, pipe, or service instance is destroyed.
A callback method that is invoked immediately after the default change detector has checked the directive's data-bound properties for the first time, and before any of the view or content children have been checked. It is invoked only once when the directive is instantiated.
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.
ProtectedNotifyProtectedNotifyHandle entity filter change
ProtectedOnCalled by the framework when query params change from an external source (browser back/forward, deep link navigation). Override in subclasses to react to query param changes.
The new query params from the URL
'popstate' for back/forward, 'deeplink' for external URL entry
ProtectedonHook for a host that instantiates CHILD resource components: re-home them here.
A host stamps its children with its tab id when it creates them, which is a SNAPSHOT. A cache reattach moves the host to a different tab without recreating anything, so a child left holding the birth tab's id would go on reading and — worse — writing that tab's params from inside a tab it no longer belongs to. That is the same cross-tab corruption this class refuses elsewhere, just arriving by a slower route, so the stamp has to move when the host does.
Default is a no-op: a component with no children has nothing to re-home.
Open the export-format-and-columns picker (mockup 26). Resolves the candidate field list from EntityInfo on the loaded metadata — no extra RunView. Default selection mirrors what the previous "export all" behavior produced.
Open a record in the entity viewer
"Preview Result" — re-runs the Quick-Operation path with the compose panel's chosen op so the user can see the expected output count before committing. We use the local set-op service rather than the server here because preview is a read-only operation that doesn't need a delta token (target is null) — staying local keeps it fast.
Re-home this component to a different tab (cache reattach across tab ids). Replaces the reactive param subscription with one bound to the new tab and resets the duplicate-delivery key so the new tab's CURRENT params apply as a fresh mount would — the replay-on-subscribe delivers them immediately.
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.
ProtectedrehomeRe-homes a child this component created to tabId.
The ParentTabId stamp is cleared FIRST and deliberately: getTabId() prefers it over the
rebound id, so leaving the old stamp in place would make the child's own RebindTabId a
no-op — it early-returns when getTabId() already matches — and the child would keep
answering with the tab it was born in. Clearing it lets the rebind be the authority, and the
child re-delivers the NEW tab's current params exactly as a fresh mount would.
ProtectedResourceProtectedUpdatePush query param changes to the URL. Creates a browser history entry. Safe to call during OnQueryParamsChanged — auto-suppressed to prevent loops.
The write is ALWAYS scoped to this component's own tab. A component that cannot identify its tab does not write at all — see the guard below.
