cant get valueChangeListener to work with Seam

[mika]

Hi,

I created a project and an entity 'myEntity' with seamgen. In the myEntity.xhml I added a h:selectOneMenu with a valueChangeListener. The valueChangeListener points to MyEntity or to MyEntityHome alternatively.

But the valueChangeListener is never called.

Any hints?

Regards,

Mika

throws AbortProcessingException {
 String s = (String) ev.getNewValue();
 category = s;
 System.out.println("Value Changed: " + s);
}
