Imports
jakarta.faces.component.UIComponent, jakarta.faces.context.FacesContext

When an instance of this event is passed to SystemEventListener#processEvent or ComponentSystemEventListener#processEvent, 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.
