please me. how remove above exception. export excel working fine.

thanks in advance.

try using clientlistener inside button prints page, stop event propagating further:

<af:resource type="javascript"> /**  * shows popup "action" type event.  * @param {adfactionevent} actionevent event being handled  */ function stopeventfrompropagating(actionevent) {   actionevent.cancel();  } </af:resource>   <af:commandbutton text="click me">   <af:clientlistener type="action" method="stopeventfrompropagating"/> </af:commandbutton>
