hm, sorry - i don't understand what the actual problem is here. Just one
thing - you probably should be careful to use replace="all" on your
submission. This will always shut down your current form - which is
probably not what you'd like to do. You cannot directly return a new
form from a submission. This won't get processed.
Instead you can use a load action to achieve the same thing.
