T4: Rewind of Form nested within a For loop

[Justin Walsh]

Hi,

I have a page containing items which the user can edit individually
using asynchronous posts.  The basic structure of the page is as
follows:


<span jwcid="@For"
         source="ognl:items"
         converter="ognl:itemConverter"
         value="ognl:item"
         renderTag="false">

    <form jwcid="@Form"
            success="listener:onCityEvent"
            async="ognl:true"
            updateComponents="errorMessage, itemList"
            delegate="bean:validationDelegate"
            clientValidationEnabled="ognl:true">

    ... form fields, for example
    <span jwcid="@Hidden" value="ognl:item.id" />

    </form>

</span>


The problem is of course that when the form is rewound, it is done
outside the context of the for loop and the value expression of the
For loop (value="ognl:item") is not set.  This presents a problem when
evaluating expressions within the form during rewind.

This _must_ be a common issue these days with rich AJAX type pages
where only part of the page is rewound.  Does anyone have a solution
to this problem?

Thanks,
Justin
