Hello,
 I didn't know what are the listeners, I studied them and now I know what 
they are :). I added the listeners in MyFactoryImpl.java in the 
createAction() and createElement() classes, and I did an Adapter to see 
that the listeners are right.
 I have studied the problem and I have seen that the true problem is that 
the label of the derived attribute isn't refreshed, i.e. when I change the 
action reference or the name of the action referenced, the value of the 
label is the same until I select the label to edit it. When I select it, 
the label takes the correct value.
 So I think the true problem is the label don't refresh automatically.

Where do I add the listener and how I refresh the label?
