richfaces - Disable button and show loading image while processing JSF -


i have module in webapp need update come catalogs.

the idea disable h:commandbutton , show h:graphicimage, both actions supposed happen right after button clicked. finally, when update process has ended should other way, hide h:graphicimage, enable h:commandbutton time show label h:outputtext says either 'update success' or 'update failure'.

the problem in code image , label appear right after process finished , can't find way described above.

where or missing?,

cheers.

    <a4j:commandbutton id="btnactualiza" value="actualizar catálogos"                        render="messagecatalogos actualizacioncorrecta                        @this imgprocesando"                        onclick="this.disabled=true;"                        oncomplete="this.disabled=false"                        actionlistener="#{administrationbean.doimgprocesandovisible}"                        action="#{administrationbean.doactualizacatalogos}"/>     <a4j:outputpanel id="imgprocesando">         <h:graphicimage rendered="#{administrationbean.imgprocesandorendered}"                         url="img/imgloading.gif"/>     </a4j:outputpanel>     <h:panelgroup/>     <h:panelgroup/>     <a4j:outputpanel id="actualizacioncorrecta" style="font-size: 14px; color: #d17100">         <h:outputtext rendered="#{administrationbean.actualizacioncorrectalabelrendered}"                       value="actualización correcta !"/>         <h:outputtext rendered="#{administrationbean.actualizacionfallolabelrendered}"                       value="fallo la actualización !"/>     </a4j:outputpanel>

update

my dev environment:

  • mojarra 2.1.6
  • richfaces 4.1.0.final
  • tomcat 7.0.14(test) / tomcat 7.0.22(prod)

you need show , hide image js instead.

<h:graphicimage id="loading" url="img/imgloading.gif" style="display:none" />

with

<a4j:commandbutton ...     onbegin="this.disabled=true; $('#formid\\:loading').show()"     oncomplete="this.disabled=false; $('#formid\\:loading').hide()" />
