I have an object that is an NSComboBox delegate. For some reason, when I
perform an editing operation in an unrelated tableView (inserting a new object
and editing it in the field editor), any new text insertion I perform in one of
3 NSComboBoxes ends up calling my delegate object twice. Is there a way for me
to find out what object is posting a -[NSNotificationCenter
postNotificationName:object:userInfo:] that eventually calls my NSComboBox
delegate?
Patrick
ps I have included a backtrace of the events prior to my delegate being called.
