Are you using T5.2? I remember T5.2 has supported partial form update.

Subject: Re: T5: Zone Update Part of Form?
Well, I'm not sure FormInjector will work without a lot of work. I
need to pass in the value of the one field and it's not clear how do
to that. The activate() method doesn't take any parameters.
For anyone else who wants to do this, here is what I did:
1. Make the zone update the ENTIRE form, which is a pain since you
can't do javascript or CSS hooks by form element ID, one has to use
class or something else. (Since the IDs change after the AJAZ
update.)
2. Use Form.serialize to save all form values before actually
triggering the AJAX update.
3. Listen for Tapestry.ZONE_UPDATED_EVENT on the zone div and re-
initialize everything in the listener. I had to re-initialize
listeners on form fields since they are all reset after the update.
One needs to use $$('select.selectClass)[0] instead of the easier $
('selectId') when passing to Event.observe.
4. In the event listener for the zone update, deserialize the form
using the handy library:
http://madchicken.altervista.org/tech/2006/02/prototype-form-serialization-and.html
This appears to behave as desired, although it's rather round-about.

FormFragement doesn't work either since it doesn't have a Form in
the Environment at AJAX render time.
I'll look into FormInjector, although I may just end up updating the
entire form, although values entered into the form before the update
are lost.

FormFragment is the way to go, or its cousin, FormInjector.

What's the best way to do this? Apparently, I can't update a zone
inside a
form that contains form fields because there is no form in the
Environment,
so rendering fails.
Will creating two forms or nested forms work? I tried a
formfragment, but
that didn't work either.
