For what it's worth, without meaning any offense, "another newbie, cry for help" is not a very good subject for your question. Remember that subjects are useful for searching and also determine who reads what sometimes. ;-)

In the NSPersistentDocument Core Data Tutorial, I have had the thing working all the way until I added the Department - now the interface all works as expected but I cannot save my data anymore. If I invoke the File -> Save As option and enter a filename the file doesn't save but I get the following logged in the Debugger Console:-


2008-03-16 19:25:43.070 DepartmentAndEmployees[6368:10b] Cannot perform operation since entity with name '(null)' cannot be found

And of course, I've found the problem, minutes after sending this. Isn't that always the way? Anyway, When I added the Department array controller to the nib I didn't set it to Entity mode. Clearly I need to read the tutorials more carefully.
