I know this is an old topic, but I recently ran into similar behavior,
researched it, and found the following in the latest NSDocument.h file
(not stated in the NSDocument reference doc):
- (void)windowControllerWillLoadNib:(NSWindowController
*)windowController;
- (void)windowControllerDidLoadNib:(NSWindowController
*)windowController;
// These methods are called when the nib loads if the document is
the nib file's owner (ie if the document implements -windowNibName).
Assuming both NSDocument and NSWindowController are both subclassed,
and NSWindowController's subclass is designated File's Owner (in the
nib file) and all the init methods are correctly implemented (as Bill
pointed out), windowControllerWillLoadNib: will never be called. In
this case, the NSWindowController's subclass's override method
windowDidLoad: will be called. In short, whatever subclass is
designated as File's Owner will get the message. I also found the
following in the latest NSWindowController.h file:
- (void)windowDidLoad;
- (void)windowWillLoad;
// These are called immediately before and after the controller
loads its nib file. You can subclass these but should not call them
directly. Always call super from your override.
I was not calling super in my override method and the header file
clearly says to do so even though the NSWindowController reference doc
says, "The default implementation does nothing." nor says anything
about calling super.
So, it pays to read both the reference docs and the header files. I
know Apple's busy and the docs are getting better, but hiding essential
information in a header file is just plain silly.

Preferrably, in its -awakeFromNib.
But NSDocument's windowControllerDidLoadNib is available when you want
the
document to notice that the nib loaded. It should work just as well as
awakeFromNib.
