This should have been expected.

Of course....if you're using raw HTML in your forms you're not using
QF as it's supposed to be used.

Hopefully this shouldn't be needed often.. Remember if you're doing
your own element you can always have a hidden element within it. You
can even extend the group element and do it that way. If you're using
a ref to the form you can most likely do it in a better way. THe only
reason SubForm has that ref is because it's a hack to make a form
within a form and I need to copy values from the main form.

Really? How, exactly? I haven't seen any examples of this yet; didn't know it was possible.
