Browseforopen works only in Test Movie

Question

Greetings,
I'm here to ask some basic help.
I have this code embedded in a Adobe Air 2 .fla :
import flash.filesystem.File;
import flash.events.MouseEvent;
import flash.events.Event;
var fileChooser:File = File.userDirectory;
function doSelect(e:Event):void
     trace (e.target.nativePath);
     var pic:Loader = new Loader();
     pic.load(new URLRequest(e.target.nativePath));
     addChild(pic);
      pic.y+=40;
fileChooser.browseForOpen("Open");
fileChooser.addEventListener(Event.SELECT, doSelect);
When I test the Movie (ctrl-enter style ^^) I can see the browse window showing up but, when I publish swf and exe version the browseforopen simply doesn't work without any error.
Is that something simple and noobish that I miss?
Thanks a lot in advance

The example in the documentation was outside any event, called like mine:
import flash.filesystem.*;
import flash.events.Event;
import flash.net.FileFilter;
var fileToOpen:File = new File();
var txtFilter:FileFilter = new FileFilter("Text", "*.as;*.css;*.html;*.txt;*.xml");
try
    fileToOpen.browseForOpen("Open", [txtFilter]);
    fileToOpen.addEventListener(Event.SELECT, fileSelected);
catch (error:Error)
    trace("Failed:", error.message);
function fileSelected(event:Event):void
    var stream:FileStream = new FileStream();
    stream.open(event.target, FileMode.READ);
    var fileData:String = stream.readUTFBytes(stream.bytesAvailable);
    trace(fileData);
I've tried anyway with button and in the test movie everything works fine, but in the app even the button won't showing up.
I've also try to do the same with a button inside the flash builder.. crtl f11 run all the funcionality. The generated app won't open the browse window.
