Description saadia dhouib CLA 2011-07-11 04:30:49 EDT 
Steps to reproduce:
1. create a composite structure diagram
2. create a class
3. create a port
4. hide the label of the port (through no connetor's label button)
5. close the model
6. reopen the model
7. try to show the label of the port

Still reproducible with Kepler 0.10.X. There is an exception.

Comment 2 Toni Siljamäki CLA 2013-10-09 10:36:57 EDT 
The same is valid for all ports = also in component diagrams,
since the port and its label are trated as separate model elements.

See additional info in Bug 417394.
