Export XML data from Reader

Hello,

I created a form with a button to export data in XML. The problem is that it only works if the form is open in Acrobat Pro. In Adobe Reader the button is not reacting despite that the extended usage rights are activated using Acrobat Pro.

The script in the button is: xfa.host.exportData("",0); (click event).

Is there a way to make it work without opening it in Acrobat Pro? I know that the alternative is to use a mail to button, but I would appreciate if there is a possibility to make it work in Reader with the export script.

Thanks and best regards.
