Could you please explain a bit more what you are expecting and what you
get? The binding code in gui is still unfinished, but basic two way
interaction should work, at least in the cases where the bindings are
already defined.
You do understand that the binding behaviour is not symmetrical? At
least not in my implementation and I think that is how Apple handles it
as well.
Did you test your code on MacOSX, was there any difference in behaviour?

This description is not that helpful :-) Could you please describe some
more what should happen? I don't have the latest renaissance test code.
Perhaps I should get that first and have a look. It may well be that you
are trying to use an unsupported binding here.
New bindings are rather easy to add in gui, I am just a bit lazy.

What did you set the sendActionOn mask to? Most likely this isn't
supported for text fields at the moment. If you come up with a
description of what Apple does, we might be able to supply something
similar.

The later is always the case, I don't know about the former :-)
