Make sure you're aware of the consequences of this. Managed objects only have a *temporary* ID until they are first saved.

That said, why not use a relationship here? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
