Perhaps I was wrong about the inverse relationship getting set KVO-
compliantly. Instead of:
newJob.rootFolder = [newJob getRootFolder];
you could try:
[[newJob getRootFolder] addAllDescendantsJobsObject: newJob];
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. Still, it's slightly disconcerting that setting the
property doesn't set the inverse relationship. How are you supposed to
change it later?
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.
Anyways, thanks muchly, onto the next part of the application!
