is there a solution [...] to implement the autosaving of expanded/ collapsed state of an NSOutlineView

I haven't done much work with Core Data so apologies if this won't/ doesn't work: I simply had a look at the headers.

Couldn't you return [[aManagedObject objectID] URIRepresentation] in outlineView:persistentObjectForItem: to save the expanded state. Then restore it by returning [aManagedObjectContext objectWithID: [aPersistentStoreCoordinator managedObjectIDForURIRepresentation:URI]] from outlineView:itemForPersistentObject:?
