Receiver type 'xxx' for instance message is a forward declaration

moving my old application to ARC, I got this error:

Receiver type 'Customer_info'  for instance message is a forward declaration

Here is my relevant code:

[params setValue:[_bill.Customer_info valueForKey:@"date"] forKey:kBillCustomerDate];

_bill is an object of a model class generated from Core Data. Customer_info is also an object of another model class also generated from Core Data and is a property in _bill's class.

Core Data is imported in the pre compiled header file app_Prefix.pch.

You need to import the entity classes, not just the Core Data headers. You description sounds like you're importing one entity but not the Customer_info entity.
