Yes, that works. As always, you must be careful you don't screw up Undo. For discussion of this, see list archives during the last couple weeks, thread: Re: CoreData and undo/redo : how to add a managed object with attributes already set in the undo/redo stack ? Several solutions are given. Gumboots asked which is "best". I don't know. They all work. An interesting question is how this happens in the DepartmentAndEmployees sample code. When I create a document with an employee, save the file and dump it with sqlite3, it appears that the Employee is related to the Department. But I looked at that code for a few minutes yesterday and can't see how it happened. The only time that an Employee is set to a Department or vice versa is in the -paste method, but that doesn't run. Does anyone know? _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
