I have verified, that if I move my class registration to before I load my NIB, then I get the correct behavior.
Your assumption therefore seems correct.

I debugged this using a sample app that Jesper provided and it looks
like this will happen if you're loading the nib file that specifies
the custom class ID before you actually register that class. This
used to work, but in Leopard we go down a different path if the class
isn't already registered and wind up creating a generic HIObject
rather than an instance of your class. That's a bug, and I'll fix it,
hopefully for a Leopard software update. However, until then, I think
you can work around this by registering your custom classes before
loading your nib file. Please try that and let me know whether it
works for you.
