Can it be that the controller is also the delegate of the window and is
your method name the same as one of NSWindow's delegate methods? Then
it will once perform the method as a delegate function, and once as a
reaction to the notification. The solution then is simply not to
subscribe to the notification. This was for my app the reason why my
NSDocument subclass reacted twice to a
WindowDidBecomeMain-notification.

Hello,
I have a very simple app where a single window is created. After it
is created, it measures a small amount of time and posts a
notification that the app controller listens for. The app controller
destroys the window , creates a new one and the whole process repeats.
The problem is the second time around, when the notification seems to
be sent twice! I am fairly positive this is the case, even logged the
events of sending and receiving the notification and that is exactly
what the log shows - one sent notification, but two received!
What's going on here? I've take all the usual precautions --
including checking which object sends the notification? I searched
and it seems some people had similar problems in the past (not fully
resolved in these forums). Any helpful suggestion?
