title: datatable: automatical refresh after a specified time
body: <p>Could you recommend me some easy way to automatically refresh of <code>dataTable</code> each e.g. 10 minutes? </p>
  
  <pre><code>&lt;rich:dataTable id="table" var="item" value="#{bean.model}"&gt;    
    &lt;rich:columnGroup&gt;
      &lt;rich:column&gt;&lt;h:outputText value="#{item.id}"/&gt;&lt;/rich:column&gt;
      &lt;rich:column&gt;&lt;h:outputText value="#{item.name}"/&gt;&lt;/rich:column&gt;
      ...
    &lt;/rich:columnGroup&gt;
  
    &lt;f:facet name="footer"&gt;  
      &lt;h:commandButton id="load" action="#{bean.loadData}"/&gt;
    &lt;/f:facet&gt;    
  &lt;/rich:dataTable&gt;
  </code></pre>
  
  <p>I've tried a few ways but it always had a catch, so I'm looking for some common method..</p>
