In my odesign file, I have a container A and its sub container B. I get a diagram for container B.First I create a diagram based on B. Then I delete its eContainer A. When I create A and create a diagram for B agian, there is some trouble.
This Diagram may need to be refreshed before opening. Would you like to refresh it now
