Vaadin6 Calendar right click on event


I’m using Vaadin Calendar 1.3.0 and I wanted to show a context menu when the user right click on an event.
The problem is that the context menu is shown only if I click in the day area (with no event). If I click on the event, nothing appends.

I implemented the getActions() method this way :

public Action[] getActions(Object target, Object sender) {
	return new Action[] { new Action("TEST") };

So it should show the context menu with the “TEST” entry each time I right click on the calendar view.

Have I done something wrong? Is it a bug?

Summary : How can I show a context menu when I right click on the event?
