Howard M. Lewis Ship commented on TAPESTRY-2360:
------------------------------------------------
I think the right fix here is that if you explicitly specify the zone's id (via
the id parameter), it is used exactly as provided.
> Forms in zones in loops have wrong zone id after update

> Key: TAPESTRY-2360
> URL: https://issues.apache.org/jira/browse/TAPESTRY-2360
> Project: Tapestry
> Issue Type: Bug
> Components: XHR/dhtml/Ajax
> Affects Versions: 5.0.12
> Reporter: Adriaan Joubert
> Assignee: Howard M. Lewis Ship
>
> When having a loop with forms in zones as in
> <t:loop source="...">
> <t:zone t:id="zone">
> <t:form t:id="f" t:zone="prop:zone.clientid">
> ...
> </t:form>
> </t:zone>
> </t:loop>
> The form updates the zone correctly on the first submit. The update handler
> returns the form (this is simpler in my application, as the zone/form is in a
> separate component) as in
> @Component
> private Form _f;
> Object onSuccess() {
> ....
> return _f;
> }
> The return value contains the markup + a script to link the form to the zone
> again. At this point the form does not know what the id was of the original
> zone, and returns a zone name of the form "zone:<number>". As the zone cannot
> be found, the whole page is refreshed when submitting the form a second time.
> To solve this from the user perspective one possibility to set the client id
> used for the zone explicitly, but this may cause problems with uniqueness of
> names.
> Ideally the javascript will return the zone id in the AJAX request, so that
> it is not necessary to track the zone id in the application. The javascript
> linking the form to the zone could then use the correct zone id.
> Thanks,
> Adriaan
