Hi George,
I've recreated the problem, but I can't spend more time on it until next week.
In the meantime, this may solve all or part of it:
- Add a zone around the form.
- Add the zone parameter to the form.
- Modify the OnValidateFromYourForm method to return an Object.
- Change the final return in OnValidateFromYourForm to return null.
- Change all the other returns in OnValidateFromYourForm to return the
zone.getBody().
eg.
<div style="margin: 20px;" t:type="zone" t:id="myZone" id="myZone">
<form t:type="form" t:id="personsedit" t:zone="myZone">
@InjectComponent
private Zone wow;
Object onValidateFromPersonsEdit() {
:
return wow.getBody();
:
return null;
}
This will not be enough if the rows have a "remove" action, but otherwise might
be OK.
Sorry, I wish I could spend more time on it now.
Regards,
Geoff
