public interface FormControllerFieldStatusListener
extends EventListener

A specialized event listener interface to be implemented by objects that are interested in status updates of form fields.

Event listeners of this type are notified by a FormController when the visited state of a form field changes, i.e. when the user leaves a form field for the first time.

The visited state of form fields may be interesting for objects that display validation results. If the data contained in a field is invalid, it may be useful to distinguish whether the field has already been visited or not. So, giving the user feedback about validation operations is the primary use case for this interface.
