I'm working with a document-based core-data OS X application. The problem I'm having is that whenever I edit any field on the document, after I press tab or click to something else (i.e. I finish editing/change focus), the document is marked as clean and undo is reset. When I try to save the file, however, the resulting document opens without the data I entered. Here's some stuff I know and things I've already tried:
I know it's not somehow saving because it never stops at the breakpoint in my overridden
and it also never sends an NSManagedObjectContextDidSaveNotification.
The documents are packaged in an NSFileWrapper directory with the core data store inside (and also some other files). I access the entities through an NSObjectController and a couple NSArrayControllers. It happens with both core data properties and manually registered changes in the rest of the file wrapper.
I tried NSUndoManager's notifications, and all I can seem to glean from it is that more than one undo manager is in play. If I add an observer for NSUndoManager, it won't post if I specify an object, and then if I don't, the notification object is not equal to [self undoManager]. I added updateChangeCount to my category on NSPersistentDocument, and it never gets called. setDocumentEdited basically confirmed that something about losing first responder is passing NO into that method.
What could be causing this, and how can I fix it?
