i don't want “result:” displayed before doaction execute/button clicked.

use rendered attribute.

<h:panelgroup rendered="#{not empty xxx_porttype_display.resultbean.result}">     <table>         <tbody>             <tr>                 <td align="left">result:</td>                 <td><h:outputtext styleclass="outputtext" id="quotacount1"                     value="#{xxx_porttype_display.resultbean.result}">                 </h:outputtext></td>             </tr>         </tbody>     </table> </h:panelgroup>
