I would need to know programmatically if a property of an UML element is changed. I'm not sure if this is more EMF/GMF related than Papyrus, but maybe Papyrus provides some help, as the changes are done via Papyrus perspective.
I guess I need something like property change listener. From where should I start in this case? Is there any tutorial?
I may not get your question right, but what about the ModelListener
extension point provided by Papyrus? You can easily provide an extension for
this extension point and you will get notified whenever a feature changed in
your model... I think this should work for you...
