public class PreValidateEvent 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 UIComponent
instance that is about to be validated.
Components with children must publish this event before processing their child nodes in
UIComponent.processValidators(jakarta.faces.context.FacesContext)
. This is especially important for iterating components such as
UIData
, and form components, such as UIForm
.
