title: <c:when> not working in PrimeFaces datatable?
body: <p>What I'm trying to do is do something to the first row, second row, etc. of the table. </p>
  
  <pre><code>&lt;p:panel header="#{mat.description}"&gt;
      &lt;p:dataTable var="datarow" value="#{myBean.getDatarows(mat.itemId)}" emptyMessage="No materials" rowIndexVar="row"&gt;
          &lt;c:choose&gt;
              &lt;c:when test="${row eq 0}"&gt;
                  &lt;p:column headerText=""&gt;&lt;h:outputText value="#{datarow.get(1)}" /&gt;&lt;/p:column&gt;
              &lt;/c:when&gt;
              &lt;c:when test="${row eq 1}"&gt;
                  &lt;p:column headerText=""&gt;&lt;h:outputText value="#{datarow.get(1)}" /&gt;&lt;/p:column&gt;
              &lt;/c:when&gt;
          &lt;/c:choose&gt;
          &lt;p:column headerText=""&gt;&lt;h:outputText value="#{datarow.get(6)}" /&gt;&lt;/p:column&gt;
          &lt;p:column headerText="Month 1"&gt;&lt;h:outputText value="#{datarow.get(1)}" /&gt;&lt;/p:column&gt;
          &lt;p:column headerText="Month 3"&gt;&lt;h:outputText value="#{datarow.get(2)}" /&gt;&lt;/p:column&gt;
          &lt;p:column headerText="Month4"&gt;&lt;h:outputText value="#{datarow.get(3)}" /&gt;&lt;/p:column&gt;
          &lt;p:column headerText="Month 5"&gt;&lt;h:outputText value="#{datarow.get(4)}" /&gt;&lt;/p:column&gt;
          &lt;p:column headerText="Month6"&gt;&lt;h:outputText value="#{datarow.get(5)}" /&gt;&lt;/p:column&gt;
      &lt;/p:dataTable&gt;
  &lt;/p:panel&gt;
  </code></pre>
  
  <p>But the c:choose and c:when is not displaying anything. Am I doing the test for row number wrongly?</p>
