Reference outer dataTable var in inner dataTable

[David Hergert]

How do you reference the variable from an outer datatable in an inner datatable? For example...

<h:dataTable border="0" 
             binding="#{mainBean.myTable}" 
             value="#{mainBean.outerList}"
             var="aRow">
   <h:column>
      <h:outputText value="#{aRow.name}"></h:outputText>
   </h:column>
 
   <h:column>
 
      <h:dataTable border="0"
                   binding="#{aRow.objTable}" 
                   value="#{aRow.objList}"
                   var="innerRow">
         <h:column>
            <h:outputText value="#{innerRow.name}"></h:outputText>
         </h:column>
      </h:dataTable>
 
   </h:column>
</h:dataTable>

It tells me it can't reference a bean by the name of aRow. I get
Error setting property 'objTable' in bean of type null
