Hi David,
I've noticed in one of Evan's exemples (repos) that he uses textarea [
value model.whatever ] [] instead of textarea [] [ text model.whatever ].
I haven't studied the reasons why, but in my tests they seem to work (and
using the second way ended up in the same bug you described).
Can you test that and get back to us?
Cheers,
