Pull Request Overview
This PR implements the ability to cancel individual occurrences of recurring meetings through a two-step modal flow. Users can now choose between canceling a single occurrence or deleting the entire meeting series, with cancelled occurrences automatically filtered from all displays.
Key Changes:
- Added backend endpoint and service methods for canceling meeting occurrences with ETag-based concurrency control
- Implemented frontend modal components for occurrence cancellation with comprehensive error handling
- Added filtering logic to hide cancelled occurrences from all meeting displays

This should be in the shared package under meeting interfaces

Use ngclass instead of individual [class.] values.

Catch error should be handled by caller
Minor improvements to the cancel occurrence feature: - Move MeetingCancelOccurrenceResult interface to shared package - Refactor delete type selection to use ngClass instead of individual class bindings - Remove error handling from cancelOccurrence service method (handled in component) - Update imports to use shared interface These changes improve code organization and maintainability.

202-204: API method looks good; keep errors bubbling to caller.Returning the raw DELETE observable with take(1) matches the prior guidance to let callers handle errors. Keep it consistent with the new confirmation dialog’s error mapping.

25-27: Harden dialog data handling (type + runtime guard).Accessing config.data.* at property init can throw if data is missing. Cast once and guard to avoid runtime errors.
Apply this diff locally and add a constructor guard:
- public readonly meeting: Meeting = this.config.data.meeting; - public readonly occurrence: MeetingOccurrence = this.config.data.occurrence; + private readonly data = this.config.data as Partial<{ meeting: Meeting; occurrence: MeetingOccurrence }>; + public readonly meeting: Meeting | undefined = this.data?.meeting; + public readonly occurrence: MeetingOccurrence | undefined = this.data?.occurrence; + + public constructor() { + if (!this.meeting || !this.occurrence) { + this.dialogRef.close({ confirmed: false, error: 'Invalid dialog data.' }); + } + }
33-58: Use finalize to avoid duplicate state toggles; map concurrency errors.Simplify spinner handling and cover 409/412 responses.
Apply this diff:
public onConfirm(): void { this.isCanceling.set(true); - this.meetingService.cancelOccurrence(this.meeting.uid, this.occurrence.occurrence_id).subscribe({ - next: () => { - this.isCanceling.set(false); - this.dialogRef.close({ confirmed: true }); - }, - error: (error: HttpErrorResponse) => { - this.isCanceling.set(false); + this.meetingService + .cancelOccurrence(this.meeting!.uid, this.occurrence!.occurrence_id) + .pipe(finalize(() => this.isCanceling.set(false))) + .subscribe({ + next: () => { + this.dialogRef.close({ confirmed: true }); + }, + error: (error: HttpErrorResponse) => { let errorMessage = 'Failed to cancel occurrence. Please try again.'; if (error.status === 404) { errorMessage = 'Meeting occurrence not found.'; } else if (error.status === 403) { errorMessage = 'You do not have permission to cancel this occurrence.'; + } else if (error.status === 409 || error.status === 412) { + errorMessage = 'Conflict detected. This occurrence may have changed or was already canceled. Please refresh and try again.'; } else if (error.status === 500) { errorMessage = 'Server error occurred while canceling occurrence.'; } else if (error.status === 0) { errorMessage = 'Network error. Please check your connection.'; } this.dialogRef.close({ confirmed: false, error: errorMessage }); - }, - }); + }, + }); }Additionally, import finalize:
- import { Component, inject, signal } from '@angular/core'; + import { Component, inject, signal } from '@angular/core'; + import { finalize } from 'rxjs';

504-546: Good occurrence selection; harden destructive-confirm UX.Logic correctly prefers selected occurrence and falls back to next active. For a permanent action, consider disabling mask-click dismissal to avoid accidental closes:
- closable: true, - dismissableMask: true, + closable: true, + dismissableMask: false,
470-502: Event naming is misleading but functionally correct; refactoring optional.All consumers of
meetingDeletedhandle both occurrence cancellation and series deletion equally:
- Dashboard refreshes the meeting list in both cases
- Modal simply closes the dialog
The naming is semantically imprecise (emitting "Deleted" for occurrence cancellation), but no consumer assumes full deletion semantics. Renaming to
meetingChangedormeetingUpdatedwould improve clarity, though the current implementation causes no functional issues.
