The NSPathControl.h file says that when in Popup mode, the control
will send a action message. However, I cannot get it to work. I've
tried using no types, and a type of "public.folder".
Is this a known problem?
I was able to create a hack work-around: use the NSPathControl
delegate method "- (void)pathControl:(NSPathControl *)pathControl
willDisplayOpenPanel: (NSOpenPanel *)openPanel" that is called just
prior to the NSOpenPanel showing. In that method send the main run
loop a message to performSelector with your IBACtion method.
When the user finishes with the open panel, the run loop dequeues
your message and sends it to your action method.

PS: from NSPathControl.h: "When the URL value in the NSPathControl
changes from an automatic drag and drop operation, or from the user
selecting a new path via the open panel, the action is sent, but the
clickedPathComponentCell will be nil."
