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.
