title: File Pointer from CreateFileAsync in Windows 8 Javascript is undefined
body: <p>Writing a Windows 8 app in Javascript using Visual Studio Express. I'm not sure if I am missing a chaining dependency or something else, but I am giving my game users the ability to save their progress into a file (at least that's the idea). However when I run the following code it appears that even though I can see the file out there, the file pointer is turning out to be undefined. See anything I'm missing?</p>
  
  <pre><code>var myStats = new Array();
  myStats[0] = myTitle;
  myStats[1] = currPage;
  myStats[2] = currStep;
  myStats[3] = currTune;
  myStats[4] = musicon;
  myStats[5] = gameComplete;
  
  var save01File = null;
  
              Windows.Storage.KnownFolders.documentsLibrary.createFileAsync("Asave01.dat", Windows.Storage.CreationCollisionOption.replaceExisting).done(
  
                  function (file) {
                      save01File = file;
                  },
                  function (error) {
                      WinJS.log &amp;&amp; WinJS.log(error, "sample", "error");
                  });
              Windows.Storage.FileIO.writeLinesAsync(save01File, myStats).done(
                  function () {
                  },
              function (error) {
                  WinJS.log &amp;&amp; WinJS.log(error, "sample", "error");
                  errCount++;
              });
              if (errCount == 0) {
                  fileMenuTitle.text = "File Saved - Click Cancel";
                  fileMenuTitle.text = fileMenuTitle.text + "\nto Return or Select Another File to Load";
                  fileMenuTitle.color = "green";
              }
              else {
                  fileMenuTitle.text = "There was an error saving that file.";
                  fileMenuTitle.text = fileMenuTitle.text + "\nPlease Make Another Selection.";
                  fileMenuTitle.color = "firebrick";
              }
