public class PreValidateEvent extends ComponentSystemEvent
When an instance of this event is passed to
SystemEventListener.processEvent(javax.faces.event.SystemEvent)orComponentSystemEventListener.processEvent(javax.faces.event.ComponentSystemEvent), the listener implementation may assume that thesourceof this event instance is theUIComponentinstance 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 asUIData, and form components, such asUIForm.- Since:
