Description Peter Lam 2008-09-09 22:23:28 UTC 
build 20080909

- create a use case diagram
- create and name a use case element
- insert and name a couple of extension points
- while the use case is selected, press Shift+Up/Down Arrow key to select an extension point
- press Shift+F10 to bring up the contextual menu for the extension point
- select Delete from the menu
- check the checkbox on the delete dialog, press OK
Result: the selected extension point should already be deleted
- now, press Shift+F10 to bring up the menu again 
Result: the following exception popped up. See attached ide log for complete exception.
