Many-to-Many Key Data

Question

I have the following data model, and I want to break the many-to-many relationship between EntityA and EntityB. I do this by removing the EntityC object that connects them both. I found that EntityA still has an association with EntityB, although I kept the context of the managed entity, I can see how the changes take effect after the EntityA records are retrieved from the database again. Am I missing something? Thanks in advance Sarah

I agree with Barry's comment, from your description it sounds like you are using more than one NSManagedObjectContext, and this will definitely cause a problem.
