core-data

I'm trying to create core data application. Some times when trying to save data, i'm seeing following error:

Error: NSInvalidArgumentException, Reason: * -_referenceData64 only defined for abstract class. Define -[NSTemporaryObjectID_default _referenceData64]!, Description: * -_referenceData64 only defined for abstract class. Define -[NSTemporaryObjectID_default _referenceData64]!

I didn't understand why this error is coming and how to avoid it. Can some one help me please.
