public class PreRenderViewEvent 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 theUIViewRootinstance that is about to be rendered.It is valid for a listener for this event to change the
UIViewRootin the currentFacesContext, but the listener must ensure that the newUIViewRootwas created with a call toViewHandler.createView(javax.faces.context.FacesContext, java.lang.String), and that the view is fully populated with the children to be traversed during render. The listener implementation may callViewDeclarationLanguage.buildView(javax.faces.context.FacesContext, javax.faces.component.UIViewRoot)to populate theUIViewRoot.- Since:
