I've override the updateListeners method with my new
removeAssociationListener, that only registers the new event listener (at
the moment it does nothig), to see if works fine and the code is executed
when I delete an association.
But there is a problem: now the associations aren't created!
Someone knows why?
The code is the following ( I have created my own associaton fig class
FigMacmasAssociation)
public class FigMacmasAssociation extends FigAssociation {
public FigMacmasAssociation(Object edge, Layer lay){
super(edge, lay);
}
public void updateListeners(Object oldOwner, Object newOwner) {
removeAssociationListener();
super.updateListeners(oldOwner, newOwner);
}
protected void removeAssociationListener(){
Model.getPump().addModelEventListener(new PropertyChangeListener() {
public void propertyChange(PropertyChangeEvent evt) {
if (evt instanceof RemoveAssociationEvent) {
// do what you want to do when this event is fired
}
}
}, Model.getMetaTypes().getModelElement());
}
}

Very thanks for all the information, actually I'm working with it
