window controller's [self window] not working

I have a window controller that I initialize using 
initWithWindowNibName.

To improve readability later in the code, I try to cache the window 
outlet to another variable. [self window] returns no value, however.

This exact same code used to work in previous incarnations of the 
program, and it seems that it simply "broke" when I opened the nib in 
IB3 and added a text field. (It was originally created in IB2 and 
worked fine in Leopard and XCode 3 until I modified it.)

I am just getting used to IB3 but don't see what or how I could have 
broken the connection. Are there any obvious culprits?

Thanks.
