can easily be reproduced with this code: String m() { String string= null; return string; } - put caret into 'string' - invoke "local rename" quick assist - press Ctrl+X to cut an entire name LinkedPositionGroup.handleEvent must use an empty String for the Replace if the document event specifies a null text. fixed > 20040924
Verified in 200411022000. Filed bug 77575 for problem with undo grouping after cut.
