[Grok-dev] Values from another document before rendering

[Kathy Manwaring]

Thanks to everyone for looking at this for me yesterday.
As I said, it was late on Friday - and obviously I wasn't thinking as
clearly as I could have been... I have worked out overnight how to deal
with this - I will use the default site value (which I can get) and then
use Ajax to amend the list of options if the user changes the site value
on the form. (Which is what I am doing in the other product).
