Adobe Reader X: TrustedFunction SaveAs

Question

Hello
I installed the new Adobe Reader X, and placed my TrustedFunction in the folder:
C:\Program Files\Adobe\Reader 10.0\Reader\Javascripts
When i test it, i always get the following error:
Error in savePdfFile(); NotAllowedError: Secutiry settings prevent access to this property or method.
i tried some settings in Adobe Reader X (like privileged locations) but nothing worked.
TrustedSaveAsPdf.js
trustedSaveAsPDF = app.trustedFunction(
  function (path){
        var retVal = "";
        app.beginPriv();
        retVal = event.target.saveAs(path);
        app.endPriv();
        return retVal;
My Call:
try {
   var retVal1 = trustedSaveAsPDF(<FILEPATH>);
} catch (e) {
   app.alert("Error in savePdfFile(); " + e);

Adobe Reader X runs in protected mode.

"Do plug-ins have read and write permissions to things like config files that maybe stored on the user's system?
Plug-ins will not be able to write log files to non-whitelisted locations. They can continue to write logs to the Temp directory (as returned by GetTempPath() Windows API or equivalent Acrobat API). Another white-listed location is Adobe Reader's own appdata area."
You can write out silently only to the whitelisted locations. The other alternative is to throw a save as dialog for user to select the location and save.
