zk popup menu EventListener onOpen fire twice

I have a Hbox like this which is attached to a Menu PopUp.

final Hbox box = ....................
final Popup pop = this.createPopUp(box);
final EventListener<Event> onOpen = new EventListener<Event>()
{
public void onEvent(final Event event){
    log.info("OnOpen");
    return;
        }
    };
popup.addEventListener(Events.ON_OPEN,onOpen);
box.setPopup(pop);
pop.setParent(box);

That's ok i have set a onOpen event listener to my popup everything works like a expected the problem is when i click in the Hbox the onOpen event is firing twice i mean i can see 2 OnOpen message this is worring because i have some DB operations in that method my question is how avoid the eventListener onOpen only fired once..

Another weird fact is the first time Hbox is clicked only one onOpen is call but from the second time the onopen method is called twice always.

My more specific code

ZUL.

What i see and i dont understand and i think is a bug suppose you have a popup open and you change the browser window or pick another popup maybe windows popup and your zk popup closes that's ok but i see when my popup closes their ONOPEN event is called why is onOpen not on_close this is some confussing...
