Will this also apply when the zone is rendered together with the form at
age loading?
Or will the submissions of the elements in the zone then go to the
form's t:formdata field?
In addition to all this FormFragment and Zone components have their own
implementation of FormSupport service that renders separate t:formdata
hidden inputs. But to use this functionality on zone you should return
whole Zone instead of just its body in event handler.
Object onUpdate() {
return updateZone;
}
So, you have a possibility to change/delete all stored process submissions
for components placed inside this zone.

Hi,
yesterday I discussed with a colleague the possibility of replacing T5
form components (parts of a form) with ajax zone updates.
The basic problem is:
- each component registers itself as "process submission" to the form (via
formsupport)
- the form serializes all those submissions to a hidden field "t:formdata"
- during submit the submissions are deserialized and executed
So it it not possible to change the submissions without replacing the
whole form. There are some workarounds that allows to add new form field by
emulating formsupport and add extra t:formdata fields to the form.
Yesterday we had an idea for a different approach which I'd like to
discuss here. What if each form field would render it's own submission to
it's own t:formdata field? In this case it would not require formsupport to
register itself to the form. The field would still be handled by the form
during submission. But the component itself could then simply be added or
removed with ajax.

Michael,
