[jira] Commented: (TAPESTRY-2073) Nested Ifs without explicit ids cause StaleLinkException

["Jesse Kuhnert (JIRA)" <de...@tapestry.apache.org>]

-----------------------------------------

Hey Ben,

I've tried to re-create this but am not getting the StaleLink exceptions that you are.   

I added the first example snippet to the TimeTracker Home.html page at the bottom (and top / middle) with various ifs before and after it but still no luck.  

Perhaps the structure of your page has some other things happening that make it harder to re-produce? (or perhaps you aren't using the latest snapshot version to test? sounds unlikely but who knows)

Will wait to see if there is another way to get it to happen.

>             Project: Tapestry
>          Issue Type: Bug
>          Components: Framework
>    Affects Versions: 4.1.4
>         Environment: Tapestry 4.1.4 snapshot from 1-22, WinXP, Firefox 2
>            Reporter: Ben Dotte
>            Priority: Critical

> The following template generates a StaleLinkException when Submit is clicked:
> <form jwcid="@Form">
> 	<outerIf jwcid="@If" condition="true">
> 		<innerIf jwcid="@If" condition="true">
> 			<span jwcid="@Insert" value="0" />
> 		</innerIf>
> 	</outerIf>
> 	<submit jwcid="@Submit" listener="listener:submit" />
> </form>
> If an explicit id is provided to either If however, it works fine:
> <form jwcid="@Form">
> 	<outerIf jwcid="@If" condition="true">
> 		<innerIf jwcid="innerIf@If" condition="true">
> 			<span jwcid="@Insert" value="0" />
> 		</innerIf>
> 	</outerIf>
> 	<submit jwcid="@Submit" listener="listener:submit" />
> </form>
> The Stale Link page indicated this error with the first template: 
> Rewind of form DirectorAccount/$Form expected allocated id #2 to be 'If_0_4', but was 'If_41' (requested by component DirectorAccount/$If_0).
> I suspect this may be caused by the changes made for TAPESTRY-1278, since this exception does not occur in 4.1.3.
