Calling XMLPORT - error Works Fine when calling from Form

nav_student

Hello guys,

use this code from the Form

   modxmlport.SetIDFilter("DocumentNo");
  _File.CREATE('C:\temp\xmlport_document\docABC.xml');
  _File.CREATEOUTSTREAM(_DatafileOutstream);
   modxmlport.SETDESTINATION(_DatafileOutstream);
   modxmlport.EXPORT;
  _File.CLOSE;

But when i apply on the Pages

View -> Page Actions
(Type Action)

appears a strange behaviour
window appears
the server "localhost:7046/DynamicsNAV" is not available. The connection was lost...

What i´m doing wrong?

Updated:
I have comment code lines one by one and the problem is on this line

modxmlport.EXPORT;
