I have found that it means I have to include the header file for the inner instance.
-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Ayers, Joseph Sent: Friday, November 05, 2010 6:13 PM To: Cocoa Dev Subject: CoreData models as structures I have a core data model that has a series of to-many relationships of the type: @interface TapeList : NSManagedObject { NSString * ListURL; NSSet* tapes; } @interface tapes : NSManagedObject { NSString * Notes; NSString * TapeName; NSSet * VideoClip; } @interface VideoClip : NSManagedObject { NSString * StartTimeCode; QTMovie * mMovie; NSString * EndTimeCode; NSString * Notes; NSString * movieURL; tapes * CurrentTape; NSSet* Table; } @interface Table : NSManagedObject { NSString * Notes; NSString * Name; NSSet* CommandStates; NSSet* Flexions; NSSet* DataSources; } A reference to tapeList.tapes works fine, but a reference to tapeList.tapes.VideoClip gives me a "request for member "VideoClip in something not a structure or union" compile time error. The structure is pretty obvious from the model see: http://dl.dropbox.com/u/2415080/datamodel.pdf but I'm baffled where it should reside in the code.
