[CS4 - JS]Export stories and "object is invalid" error

Question

Hello all,
I need a javascript script that exports all the stories of a document to .icml files.
At the moment I've come to a function like this:
function exportICML(myDoc, path) {
        var stories = myDoc.stories;
for (var i = 0; i < stories.length; i++) {
      alert(i);
      var story = stories.item(i);
      var filename = path + "/story-" + i + ".icml";
      try {
           story.exportFile(ExportFormat.INCOPY_MARKUP, new File(path));
             } catch (err) {
alert(err.message);
This function fails, and in the server log I see this error:
"Object is invalid"
What am I doing wrong?
Thanks.

Works fine here :S
var myDoc=app.activeDocument;
var myPath = Folder.desktop+"/test.icml";
exportICML(myDoc, myPath);
try storing theend of loop outside the function and renaming var to avoid DOM names collision.
function exportICML(myDoc, path) {
        var allStories = myDoc.stories;
var iMax = allStories.length;
for (var i = 0; i < iMax; i++) {
      alert(i);
      var myStory = allStories.item(i);
      var filename = path + "/story-" + i + ".icml";
      try {
           myStory.exportFile(ExportFormat.INCOPY_MARKUP, new File(path));
             } catch (err) {
  alert(err.message);
