[jira] Commented: (TAP5-453) FormFragment does not work in a loop

["Howard M. Lewis Ship (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TAP5-453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12678490#action_12678490 ] 

Howard M. Lewis Ship commented on TAP5-453:
-------------------------------------------

This is related to how the FormFragment inherently operates, breaking the stream of component actions into per-fragment pieces. I'm not sure of a way to resolve this.

> When using a formfragment in a loop, the form data is not saved correctly (the loop itmes are iterated before the data in the formfragment is saved. The end result is that all changes are put in the last item from the loop.
> Using the following template
> {code}
>         <t:loop source="list" value="current" volatile="true">
>             <div t:type="FormFragment" visible="true">
>             <input t:type="TextField" maxlength="50" size="50" value="current.content" />
>             <br />
>             </div>
>         </t:loop>
> {code}
> the data is not stored correctly, while this works.
> {code}
