I have found that it means I have to include the header file for the inner instance.

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:

but I'm baffled where it should reside in the code.
