[Tomahawk] t:dataTable with dynamic columns

[Francisco Passos]

Good day to all.

I have a List<List<MyType>> (attribute.tableAttributeData) and am trying to
present it in a table like this:

<t:dataTable value="#{attribute.tableAttributeData}"
var="lineAttributeData"  >
  <t:columns value="#{lineAttributeData}" var="attributeData">
    <f:facet name="header">
      <t:outputText value="#{attributeData.inomcol}" />
    </f:facet>
    <h:outputText value="#{attributeData.xvalor}" />
  </t:columns>
</t:dataTable>

However the table does not appear at all. Did I miss something?
