ComboBox with beans never calls ValueChangeEvent

Hay there,

I need help with a ComboBox.
I added a beancontainer and this works as far as a charm,
but then the ComboBox is never fireing any event when changing the value.

        dd_marke.addValueChangeListener(new Property.ValueChangeListener() {
            public void valueChange( event)
            System.out.println("Value was changed to "+dd_marke.getValue());

The direct listenerevent AND the Listener control I added, never have been called.
Where is the problem here?

Problem solved. I don’t know why, but after hours of waiting it works now… I have nothing changed.
