Class PreRenderComponentEvent

All Implemented Interfaces:
Serializable

public class PreRenderComponentEvent 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 rendered and that it is safe to call UIComponent.getParent(), UIComponent.getClientId(), and other methods that depend upon the component instance being in the view.
