No. F5 is a way to execute Canonical update for the selected diagram element 
(synchronize diagam element structure with an underlying domain model one).

You are right - ciorresponding update should be performed by GMF-generated 
code automatically. We have some problems with diagram update on link rerouting/deleting, 
but it looks like not your case.
Can you try prassing F5 to update diagram after customized execution? You 
need to select parent element of the element you've modified/added/deleted 
and press F5. 

> Are GMF bugs generating this incorrect situation?
Definitely there can be some problems with diagram update, but I'd like to 
ensure the problem is in update process, so I suggest you pressing F5 ad 
debugging generated ???DiagramUpdater if F5 is not working to see if the 
problem is in diagram update..

BTW, another posibility to refresh diagram is to close it and reopen again 
- diagram content should be updated on diagram openning.

No. ???CanonicalEditoPolicy classes generated for each diagram element are 
responsible for listening for any notifications from EMF and updating diagram 
in accordance.
