I have NSManagedObject with identity attribute. This object has several nullable properties. I set values for these properties and save NSManagedObjectContext. When I get JSON from server containing list of objects I want to merge these changes with my existing objects. Although corresponding attributes are null my saved properties are replaced with these nulls.
