Description

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.
