title: h:dataTable backing bean not called
body: <p>In the JSP I am using an <code>h:dataTable</code> tag with value set to point to my getter method, which in turn returns a list of objects. The problem is that the <code>getListSignataireExceptions</code> is never called and the table is empty.</p>
  
  <p>Please note that the <code>AdministrationBean</code> is well initialized, and if I put <code>#{administrationBean.listSignataireExceptions}</code> outside the table tag, I get the list of objects on the screen in non formatted way.</p>
  
  <p>Same goes for <code>#{administrationBean.message}</code> - no message, the backing bean is not called.</p>
  
  <p>JSP:</p>
  
  <pre><code>&lt;div class="content"&gt;
      Administration des Exceptions signataires
      &lt;h:dataTable id="table1" value="#{administrationBean.listSignataireExceptions}" var="item"
                   border="1"&gt;
          &lt;f:facet name="header"&gt;
              &lt;h:outputText value="Your Shopping Cart" /&gt;
          &lt;/f:facet&gt;
          &lt;h:column&gt;
              &lt;f:facet name="header"&gt;
                  &lt;h:outputText value="Item Description" /&gt;
              &lt;/f:facet&gt;
              &lt;h:outputText value="#{item.idSociete}" /&gt;
          &lt;/h:column&gt;
          &lt;h:column&gt;
              &lt;f:facet name="header"&gt;
                  &lt;h:outputText value="Price" /&gt;
              &lt;/f:facet&gt;
              &lt;h:outputText value="#{item.idAnnuaireSalarie}" /&gt;
          &lt;/h:column&gt;
          &lt;f:facet name="footer"&gt;
              &lt;h:outputText value="Total: #{administrationBean.message}" /&gt;
          &lt;/f:facet&gt;
      &lt;/h:dataTable&gt;
  &lt;/div&gt;
