I left the old Xcode 3 example in the Git repo, can you please give it a
try?
https://github.com/mattetti/MacRuby--The-Definitive-Guide/tree/master/chapter_7
Or maybe I misunderstood and you are saying that the example works but your
code doesn't?

If that's the case make sure your Actors array controller is set properly,
here is a screenshot from when the code was running under Xcode 3:

And make sure you are trying to set the bindings properly, kind of like in
this Xcode 3 example for movies:

The other thing you can check is that the Table Column is marked as
editable (in the table column settings).

p130, the explanation for choosing another cell class doesn't work: In the

In Xcode 4 it autocompletes... it might be a problem with Xcode 3 behaving
differently, sorry. But I'm glad you found a workaround,

One more thing :)
