java - how to update information on a popup window while the execution continues -

i have cancel popup custom ok button confirmation , i'd update progress information on execution goes on.

popup follows

<af:popup id="confirmationpopupsend" binding="#{pageflowscope.bean.confirmationpopup}" contentdelivery="immediate">     <af:dialog id="confirmationdialogsend" modal="true" title="confirmation" type="cancel">       <f:facet name="buttonbar">         <af:commandbutton id="confirmdialogbuttonsend" text="ok" action="#{pageflowscope.bean.submitaction}"/>       </f:facet>       <af:outputtext value="are sure? might take while."/>       <af:outputtext visible="#{pageflowscope.bean.someprogress> 0}"          value="#{pageflowscope.bean.someprogress}" />     </af:dialog>   </af:popup> 

my submitaction method follows

    public string submitaction()     {         for(some condition){              //update variable someprogress              refreshloadingpopup();         }     } 

and refresh method

public string refreshloadingpopup(){     facescontext context = facescontext.getcurrentinstance();     uiviewroot root = context.getviewroot();     uicomponent c = findcomponent(root, "confirmationdialogsend")     adffacescontext.getcurrentinstance().addpartialtarget(c); } 

the problem here refresh method works. checked putting test button on popup window , updates information when put refresh method inside submitaction method, nothing happens on popup window execution continues. once submitaction ends execution, popup closes anyway.

i want show progress user. other approach welcome, too.

thanks

you can't update popup calling refreshloadingpopup method. following line marks component c refreshed.

adffacescontext.getcurrentinstance().addpartialtarget(c); 

while request being processed (the loop in submitaction method executing) client not have response , component c not refreshed.

you should continue update pageflowscope.bean.someprogress property in loop , make client poll value i.e. every 0.5 seconds.

you can use af:poll component requirement. here example shows how use af:poll component: http://www.oracle.com/technetwork/developer-tools/adf/learnmore/42-progressbarcolor-169184.pdf
