title: DisplayTag doesn't work inside a forEach tag
body: <p>I'm trying to render a DisplayTag table inside a forEach loop. The expression <code>${paquete.listaProductoPaquete}</code> is a one item list; but when I try this I get an empty table:</p>
  
  <pre><code>&lt;c:forEach var="paquete"
      items="${consultaConsumosWrapper.listadoPaqueteConsumo}"&gt;
      &lt;tr&gt;
          &lt;td&gt;&lt;display:table
                  name="${paquete.listaProductoPaquete}" export="false"
                  id="producto" style="width:100%" sort="list"
                  defaultsort="1" class="grilla"&gt;
                  &lt;display:column sortable="false"
                      titleKey="header.consultaDatos.producto"&gt;
                      ${producto.producto}
                  &lt;/display:column&gt;
              &lt;/display:table&gt; 
              &lt;/td&gt;
      &lt;/tr&gt;
  &lt;/c:forEach&gt;
  </code></pre>
  
  <p>If I try this, I get the information of the single item on the list as expected:</p>
  
  <pre><code>&lt;c:forEach var="paquete"
      items="${consultaConsumosWrapper.listadoPaqueteConsumo}"&gt;
      &lt;tr&gt;
          &lt;td&gt;
              &lt;c:forEach var="producto"
                  items="${paquete.listaProductoPaquete}"&gt;
                  ${producto.producto}
              &lt;/c:forEach&gt;&lt;/td&gt;
      &lt;/tr&gt;
  &lt;/c:forEach&gt;
  </code></pre>
  
  <p>Any ideas why this isn't working? When I try the tag outside a loop anything goes normal.</p>
