Thanks again for your help, and thanks in particular for your follow-up email,
which was a great help in working out the bindings (it was indeed the first
time I'd done anything like that!). I have a couple of follow-up questions if
you don't mind.
Question 1 - you state "Nothing in any of this will or should have any effect
on what's selected in the text field where editing was in progress", but if we
are both talking about the same thing then I don't think that's happening for
me. The screenshots before and after clicking the "send" button (which triggers
a commit) are shown here:

The text field has lost focus. Would you expect this to happen? Does this
suggest that I've slipped up somewhere in how I have wired everything up
together or something?
Question 2 - the method you have described seems to be very much tied to a
single NSObjectController for the entire window, and indeed IB just seems to
offer the option to bind to "Object Controller", without specifying "which
one". In that case, is there any way of achieving neat group-based behaviour
for the following window?

Here there are two separate categories of editable fields. If "send" is clicked
then it is important that any edits to the stage command field are committed,
but I think it would make more sense if ongoing edits to the "stage limits"
fields are NOT committed if "send" is clicked (they are completely irrelevant).
n.b. the window does not close when "send" is clicked. Is there any way of
achieving this?
Cheers
