      org.apache.cocoon.forms.event.WidgetEvent
          org.apache.cocoon.forms.event.ValueChangedEvent
              org.apache.cocoon.forms.event.DeferredValueChangedEvent

All Implemented Interfaces:

Serializable

public class DeferredValueChangedEvent
extends ValueChangedEvent

A ValueChangedEvent that defers getting the new value from the widget until it's actually requested.

This allows widget validity to be checked only if a listener actually uses the value, thus avoiding unnecessary validation warnings when a user clicks an action.
