public class PreRenderViewEvent extends ComponentSystemEvent
When an instance of this event is passed to SystemEventListener.processEvent(jakarta.faces.event.SystemEvent) or
ComponentSystemEventListener.processEvent(jakarta.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(jakarta.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(jakarta.faces.context.FacesContext, jakarta.faces.component.UIViewRoot) to populate the UIViewRoot.
