#8 collection editor does not allow renaming

[S M]

Class Diagram
- Add a class box.
- Add properties using Model > Collection Editor
(<ctrl><f5>).
- Rename the new attribute using right-click "Rename"
(<f2>). </f2></f5></ctrl>

It simply does not rename the attribute. The only way
to rename is to use the mouse pointer and double-click
on the attribute inside the class box.
