umbraco-validation-context

Use UmbValidationContext to orchestrate validation across complex Umbraco backoffice UIs like multi-step forms. It binds validation to individual inputs reactively, eliminating the need to manually wire error messages for each field or tab.

Observe validation message streams with messagesOfPathAndDescendant to compute reactive error counts per section. This approach drives UI badge displays in Umbraco workspace editors by tracking JSON Path-targeted validation messages.

Add server-side validation errors directly into the UmbValidationContext after an API response. This integrates them with client-side errors in the same context, allowing you to clear outdated server errors between submission attempts.

JSON Path targeting attaches validation bindings and messages to specific paths like $.form.tab1.email. This structure keeps validation organized across multi-step forms and allows precise observation of descendant validation states.

Yes, umbBindToValidation supports multi-step Umbraco form components. It binds fields directly to the centralized UmbValidationContext, ensuring validation state is accurately tracked and observed reactively across all steps.

Ensure you actively remove outdated server-side validation messages from the UmbValidationContext between API response attempts. This maintains a clean validation state and prevents stale errors from persisting across new submissions.
