Java Development Tools

Jdev 11.1.1.7

I have a popup written as:

<af:popup id="p2"

           binding="#{pageFlowScope.AIMSAdminTemplateBean.navigateToOtherPagePopUp}"

           contentDelivery="immediate">

        \<af:dialog id="d2"

                   dialogListener="#{pageFlowScope.AIMSAdminTemplateBean.deleteCurrentData}">

          \<af:outputFormatted value="You might loose the data on current page. Do you wish to Continue? " id="of1"/>

        \</af:dialog>

      \</af:popup>

The Dialog is okcancel type(default).

I need to implement immediate =true for the ok button in this case . please advise
