Are the listing from two different GDB sessions? Otherwise, judging from the value of self in [MyDocument makeWindowControllers], you have TWO instances of the MyDocument class. Is this intentional? On May 4, 2009, at 3:38 AM, David Scheidt wrote:

I'm trying to figure out why my NSPersistantDocuement subclass's - makeWindowControllers is getting called twice. I'm also trying to figure out why a nib that I'm trying to load from a viewcontroller created by the window controller made by -makeWindowController isn't loading. I'm willing to bet they're related. I'm further willing to bet it's something I've done, but I'm stumped.
