Use exhaustMap in Angular reactive forms to ignore subsequent submissions until the current Observable completes. This prevents concurrent dialog form submissions and ensures safe, sequential data processing for create and edit workflows.

Track Angular form status with signals by applying startWith to ensure correct initial state emission. This signal-based status tracking provides reliable form validation updates for reactive forms throughout the component lifecycle.

Configure typed Angular forms using a typed FormGroup and FormControl to enable robust type-safe form handling. This supports create and edit workflows by allowing existing data to be patched into the form dynamically.

Angular form submission uses takeUntilDestroyed with DestroyRef to automatically manage subscription cleanup. This prevents memory leaks in dialog components by ensuring exhaustMap-based submission observables are properly destroyed.

The exhaustMap submission pattern intentionally ignores concurrent submissions while a form save is in progress. This prevents duplicate network requests and ensures the dialog form processes only one submission at a time sequentially.
