Guillaume Avril commented on MYFACES-4757:
------------------------------------------
Create a custom SystemEventListener with :
@override
public void processEvent(SystemEvent pEvent) {
FacesContext facesContext = FacesContext.getCurrentInstance();
facesContext.getApplication().unsubscribeFromEvent(PreRenderComponentEvent.class,
UIComponent.class, this);
}
Have it registered (like, when you click on a button, or something like this)
with :
FacesContext facesContext = FacesContext.getCurrentInstance();
facesContext.getApplication().subscribeToEvent(PreRenderComponentEvent.class,
UIComponent.class, new MyCustomSystemEventListener());
It should be enough to reproduce
> ApplicationImplEventManager.processGlobalListeners throws
> ArrayIndexOutOfBound when a SystemEventListener unsubscribe itself during
> processEvent
