Hello,
I ran into the same problem. My app delegate's +(void)initialize
method was too late to register the value transformer that was used in
the nib that was loaded on startup. Registering before
NSApplicationMain() works, but it doesn't seem like the right way to
me. Is this a bug in Cocoa?
Thanks,
Johan Kool
