public class PreValidateEvent extends ComponentSystemEvent
When an instance of
 this event is passed to SystemEventListener.processEvent(javax.faces.event.SystemEvent) or
 ComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener
 implementation may assume that the source of this event
 instance is the UIComponent instance that is about to be
 validated.
Components with children
 must publish this event before processing their child nodes in
 UIComponent.processValidators(javax.faces.context.FacesContext).  This is especially important for
 iterating components such as
 UIData, and form components, such as UIForm.
