I'm assuming you have the book (2nd ed).
---

I'm angry because the editor missed some real editor things - not technical:

- things like parallelism
- thought encapsulation
- backreferencing previous discussions

We can't do anything about that, but I'm hoping that maybe someone on this list can help with some of the technicalities of this book.

I'm particularly baffled about the mention of setEmployees: under the heading "adding undo to raiseman". Why is this function here? I think it's so that the NSArrayController can talk to MyDocument -- but what calls it? I understand the retain and release etc. -- but when is this called, by what, is this part of the default behavior of NSArrayController?

--

p. 146 - How does the insert: message equate into the just explained 'insertObject:inEmployeesAtIndex" ?

Anyone able to explain these bits?

Thanks,

Steven
