Problem setting to-one relationship on NSManagedObject

Subject: Problem setting to-one relationship on NSManagedObject
From: Jim Majure <email@hidden>

I'm using the following code to create a new Core Data entity and populate a to-one relationship. Everything seems to be working okay except the "setValue:forKey:" to establish the to-one relationship. I've included the error messages below. Any ideas what I might be doing wrong?

Thanks,
Jim

NSManagedObject *newTimeEntry = [NSEntityDescription insertNewObjectForEntityForName:@"TimeEntry" inManagedObjectContext:[selectProjectController managedObjectContext]]; NSManagedObject *project = [selectProjectController selection];

	[newTimeEntry setValue:project forKey:@"project"];
