Mac OS X 10.5.2 I have NSOutlineView bound to NSTreeController Additionally, I have a button, which is bound to "canRemove" of NSTreeController. Unfortunately, button never gets disabled (even if I have an empty selection in NSOutlineView)
I added NSLog() to the method, which handles click on button and put value of "canRemove" — the value is correct there (NO when nothing is selected, YES, when something is selected). Visually, whenever I remove selection in NSOutlineView button gets disabled for half-a-second, and then becomes enabled again. What can be done to solve this issue? -- Alexey Zakhlestin http://www.milkfarmsoft.com/
