Hi Creighton
Did you get anywhere with the wraps you mentioned?
I couldn't get your above code to work, it still was causing cursor movement
when I changed values, so had to remove any setting of :value in the
custom-transform.
I ended up not needing to have initial values in the form data, which was fine
as the form being blank to start was ok, but now I've have the need to set
initial values in the form on first render, and i'm still trying to work out
how to do this, e.g. {:name "foo"} on entry, then the name field should contain
the text "foo" but allow normal editing.
