NB: 200709232115 Steps to reproduce: 1) Create a UML Java Platform model project, create a class diagram 2) Create 2 class elements (Class1, Class2) 3) Add 2 operations (op1, op2) to Class1 4) Connect a generalization link from Class2 to Class1 5) Redefine dialog appears, select checkbox for Class1 6) From the editor, right click Class2 -> Redefine Operations Redefine dialog came up but is empty (see attached screenshot) 7) From the Projects window, right click Class1 -> Redefine Operations There is nothing come up, no dialog. This also causes confusion to the user. Observing a couple problems here and request for enhancement to improve usability: 1) From the editor, Redefine Operation menu item should be grayed out/or disabled if there is nothing to be redefined 2) From the Projects window, if no more option can be selected for the class element, request to gray out/or disable the menu item instead of showing an empty dialog

Clarification on the request: 1) From the editor, Redefine Operation menu item should be grayed out/or disabled if there is nothing to be redefined instead of showing an empty dialog 2) From the Projects window, if no more option can be selected for the class element, request to gray out/or disable the menu item instead of nothing coming up
in addition to the last #2 comment, the menu item should also be disabled or grayed out from the diagram editor for the selected class.
