FormPanel "Show" event no longer fires after upgrading to 2.2.5

[playalpha]

I have tried every possible permutation of the following and I need some help. This all used to work until I upgraded.

MyFormPanel(){

addListener(Events.Show, new Listener<BaseEvent>() {

@Override
public void handleEvent(BaseEvent be) {
Window.alert("show");
}
});

}

I tried overriding onShow() as well as adding the listener in onRender(). Nothing happens.

What are you trying to do? The show event fires after you call the show method.

I have a requirement to make the FormPanel fields behave as though they were Web 1.0 and clear if you show-hide-show the form.

Previously, Observable was invoking my onShow() method every time the form was shown, and I could just call clear() as below and it would work as expected. Now this no longer happens, my handler is never invoked.

@Override
protected void onShow() {
super.onShow();
clear();
}

Hi Sven, does the framework not invoke onShow() automatically when FormPanel is shown? Do I misunderstand? It sounds like you're saying I need to call it in my code. If so, how would I add a handler to be notified when this happens?

Any ideas?

The framework only calls onShow when you really call the show method. Not when you simple add the Component to the DOM.

Do you have a fully working testcaes implementing EntryPoint that shows exactly what you are doing?

Hm, I tried this with a fresh project and it appears to work correctly. In my existing large application (~20k lines of code) it is not working anymore.

Any help on common pitfalls in this area would be appreciated.

Thanks,
