public class PreRenderViewEvent 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 UIViewRoot instance that is about to be
rendered.
It is valid for a listener for this event to change the UIViewRoot in the current FacesContext,
but the listener must ensure that the new UIViewRoot was
created with a call to ViewHandler.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 call ViewDeclarationLanguage.buildView(javax.faces.context.FacesContext, javax.faces.component.UIViewRoot) to populate
the UIViewRoot.
