Hi, star123,
If your application uses a GMF-based diagram editor, then it already
employs a TransactionalEditingDomain. This gives you a "trigger" API
with which you can react to changes in the model to follow up with
additional edits such as copying the ports.
There is a tutorial and other documentation in the "EMF Model
Transaction Developer Guide" in the on-line help. This is assuming, of
course, that you have installed the EMF Model Transaction SDK.
Otherwise, find it here:
http://help.eclipse.org/
HTH,
Christian
