E para que serve os atributos abaixos ?

1- getOrigin()

2- getTarget();

Hi hermesmenezes,

When you add a listener to the component, you can retrieve a event instant in the listener, e.g. if you listen a onClick event you will retrieve a MouseEvent instant, and the target is the component that you bind the listener to, if you add a forward event,

button.addForward("onClick", window, "onDoAdd")

the event will be a forward event.

public void onDoAdd(Forward event) {
      event.getTarget(); // window
      MouseEvent mevent =  (MouseEvent) event.getOrigin();
      mevent.getTarget(); // button
}
