Thanks for the feedback. As a matter of fact, after sending my
question, I realized that the employee ID text field shouldn't be
altered and when I looked at the "bind" check box in its inspector,
it was checked. I have no recollection of having done this (but
then, neither do I remember lots of other things that I should!).
Anyway, the problem has been solved.

When the user interface is automatically created by Interface
Builder following the instructions in the tutorial, 3 array
controllers are created, two of which are for employees. When I
used the NSTextFieldInspector for "Employee ID:" in the interface,
it was bound to Employee Array Controller 2 (NSArrayController)
rather than Employee Array Controller (NSArrayController).
Changing this to Employee Array Controller (NSArrayController),
that is, to the other NSArrayController that was automatically
created, fixed the problem.
Question: Is there something in the tutorial that I missed, or is
the tutorial deficient in not making explicit which
NSArrayController Employee ID is supposed to be bound to? Or is
the step I missed so obvious that someone more experienced with
Cocoa would be expected to know it and therefore it was left out
of the tutorial?
The tutorial does not require that the employee ID text field be
altered. Interface Builder creates the user interface
automatically, and I can't offhand think of any reason why it
should make an erroneous connection as you describe. What happens
if you remove the existing user interface elements and the
controllers, and recreate the UI from scratch (as described in
<http://developer.apple.com/documentation/Cocoa/Conceptual/
NSPersistentDocumentTutorial/02_CreatingProj/
chapter_3_section_4.html>)?
