I've appended to this email a patch for clearing a form after it has
been processed so it can be rendered again in one request. After some
light unit testing, it seems to work well. Intended usage is:
form = self.build_some_form() # Form will post back to this exported
method.
if form.is_submitted() and not form.has_errors():
# process form....
form.clear()
form.render()
If you use the prefix keyword on the Form constructor, you can mix
many of these in one exported method.
