Hello Matt.
What caused my confusion, is that the docs DO say that the content-
property is observable with KVO. When it wasn't, I thought that I was
doing something wrong, and that's why I posted this question.
Your alternative solution with notifications was a good idea, thank you.
Bill: thanks for correcting his typo.

Okay, I think it doesn't work because I bind to
collections.arrangedObjects. But what should I bind to instead, to
get the functionality I want?
Hannes - I have not been following this thread, so maybe this is
not the
answer you need, so please forgive me if I'm off the mark. But you
seem to
be saying you need to know what the added object is whenever an
object is
added in an NSArrayController.
If so, it seems to me that your mistake here is thinking that you
have to do
this with bindings. Bindings don't do everything! Remember, we all
lived a
very long time and very comfortably without them. What I do in a
similar
situation is simply to override add: in the NSArrayController and
post an
NSNotification containing a pointer to the newly added object. m.
