    Anybody having problems with the mapping model in xcode 4 using 4.3 ios? I use the same mapping model on the xocde 3.2.5 and run it on 4.2 or 4.1 and it works fine. Is there something we have to add to xcode 4 to get it to work?

    This is the error I get:

    Unresolved error Error Domain=NSCocoaErrorDomain Code=134140 "The operation couldn’t be completed. (Cocoa error 134140.)" UserInfo=0x1a9ae0 {destinationModel=(<NSManagedObjectModel: 0x17e2c0>) isEditable 0, entities
