I have menu bar and when ever the user double clicks on it 2 events are getting generated. So if I do a save by double clicking on a Menu Item, Vaadin is sending two click events and menuSelected is getting called twice.
Is it a bug in Vaadin? if not how do I prevent this.
If you double click you should be getting a double click event and not two single click events so I think you have a case to file a bug ticket for it in the trac. Adding a simple test case to the ticket always improves the chances of it getting fixed sooner.
