Extension reset button

Hello forum members,

I use a reset button in my form with this script:

var returnValue = app.alert("Are you sure?",2,2);

if (returnValue == 4) //yes is 4, no is 3
{xfa.host.resetData();xfa.form.remerge();}
else
null;

Is there an extension to the script which makes the form "jump" to the first page? With this script the form stays at the last page.

Thanks.
