I have seen behavior like this when, for instance, the contents that
a popup is bound to disappear, but the corresponding instance
variable is not set to nil to notify the observers.
I assume this has something to do with the magic "KVO" object stand-
ins that get generated by the bindings system. That would explain
how they still know enough about what they are bound to identify it
by class name, but since the underlying object has disappeared there
are not real details to convey to the UI.

Are you using an actual property key to display the title, or
relying on 'description'?
See, for example, <http://www.cocoabuilder.com/archive/message/

I was using a property key.
I must admit, I have a difficult time understanding which bindings
to use. In the present instance, though I'm not using core data, I
went back to the core data tutorial and tried copying the bindings,
but didn't get the result I expected.
Thanks
