Is there a way I can know from the wrapping external component (angular) if a form is finally valid in all it’s fields?

Hi @otrebor,

The JSON Forms root component in [Angular provides an `errors @Output`](https://github.com/eclipsesource/jsonforms/blob/24f4e5f6280263a4b8e1263aa2a302613b546272/packages/angular/src/library/jsonforms-root.component.ts#L70). Once you receive an empty array, the form is valid.
