RichFaces a4j:support parameter passing

Question

Hello

I have a number of rich:inplaceInput tags in RichFaces which represent numbers in an array. The validator allows integers only. When a user clicks in an input and changes a value, how can I get the bean to sort the array given the new number and reRender the list of rich:inplaceInput tags so that they're in numerical order?

EG

<a4j:region>
    <rich:dataTable value="#{MyBacking.config}" var="feed"
        cellpadding="0" cellspacing="0" width="100%" border="0"
            columns="5" id="Admin">
...
<a4j:repeat...
    <a4j:region id="MsgCon">
        <rich:inplaceInput value="#{h.id}"
            validator="#{MyBacking.validateID}"
            id="andID" showControls="true">
            <a4j:support event="onviewactivated" action="#{MyBacking.sort}"
                reRender="Admin" />
        </rich:inplaceInput>
    </a4j:region>
</a4j:repeat>
</data:Table>
</a4j:region>

Note I do NOT want to use dataTable sort functions. The table is complicated and I've specified id="Admin" (ie the whole table) to reRender as I've not found a way to send more localised values to the backing bean through the inplaceInput. This question is about how to use a4j:support action attribute to call the sort method so that when the reRender rerenders the component, it outputs the list in sorted order.

I have the sort method working ok when I click a button to sort, but I want to have the list sorted automatically as soon as a new valid value is entered into the inplaceInput component.

Thanks
