That worked! The result was wrong, but making the rootFolder relationship into rootFolders and making it to-many, changing getRootFolder to -(NSArray *)allContainingFolders, and sending everything in that the addAllDescendantsJobsObject: message worked perfectly.
Good news. :)
Still, it's slightly disconcerting that setting the property doesn't set the inverse relationship. How are you supposed to change it later?
I believe it *was* setting the inverse correctly, just not KVO- compliantly. That is, your data model was correct, but the user interface was out-of-date.
On a mostly unrelated note, is the only way to suppress the "no '- addJobsObject:'/'-addAllDescendantsJobsObject:' method found" warnings to create the Folder custom subclass and paste the Core Data method declarations in? That approach seems like overkill since I have nothing to customize in it.
I forgot, you can't use @dynamic because these aren't properties. What you can do is put the method declarations in a category of your subclass, and just not implement the category. See Xcodes's Design --> Data Model --> Copy Obj-C 2.0 Method Declarations to Clipboard as a way of avoiding re-inventing this for yourself. (But delete any #ifdef'd stuff it gives you -- that's only if you're actually re- implementing the methods.)
