MainMenu.nib is loaded first, when applicationHasFinishedLoading,
Login.nib is loaded. The userController is instantiated in Login.nib.

I was hoping it would work since the object that references
userController is the same object. After the login panel is done,
userController has been instantiated and filled with data. I can get
data out of it but Cocoa bindings won't display data from it. It seems
more a nib synchronization thing. Since userController is not connected
to anything in MainMenu.nib, the main window isn't getting data from
it? I guess I could make a loginController, then copy the data from
that controller to userController once the login panel is dismissed.

saved me, this seems a small price to pay :)

I wasn't aware. Thank you.
