ajax4jsf support <t:dataList>: reRender one element of tomahawk dataList
------------------------------------------------------------------------

                 Key: RF-8092
                 URL: https://jira.jboss.org/jira/browse/RF-8092
             Project: RichFaces
          Issue Type: Feature Request
          Components: component-a4j-core
         Environment: ALL
            Reporter: Dave Chen



<t:dataList  id="employees" var="e" value="#{bean.employeeList}">

    <h:panelGroup id="info">
         <h:outputText value="#{e.name}"/>
         <h:outputText value="#{e.addr}"/>
         <%--- more info ---%>
    
    </h:panelGroup>


</t:dataList>

<a4j:commandButton action="#{bean.refreshEmployee2}" reRender="employees:2:info" />

We hope the action will reRender the 3rd employee only.   Currently we have to refresh the whole employee list.

   <a4j:commandButton action="#{bean.refreshEmployee2}" reRender="employees" />

For a list of 100 employees, it will have a big performance/network overhead.
