Core Data - synchronize ManagedObjectContexts - save date

Subject: Core Data - synchronize ManagedObjectContexts - save date
From: Rainer Standke <email@hidden>

Hello,

I have an document-based CoreData application that uses an NSOperation to manipulate ManagedObjects. I can successfully synchronize the main thread's context, using mergeChangesFromContextDidSaveNotification:.

However, when I subsequently try to save the document I get a warning that the doc has been saved by another application. This happens in spite of the fact that I update the doc's fFileModificationDate right after synchronisation.

What am I missing?

Thanks,

Rainer
