Excellent! That's the piece I was missing! I didn't know what to put for the
path. I still don't think it's very intuitive. I thought path referred to a
getter in your command object. Which I thought was quite limiting as you
wouldn't be able to use it for other objects in the request. But now I see
it can work with any old object. But I am curious why 'country.id' is used
as the path. Is the path nothing more than the name of the form input id you
send to the server when you submit?
At any rate, I'll try it first thing in the morning at work.
Many thanks!
