title: PhoneGap's FileTransfert Success Callback error
body: <p>I'm using PhonGap's FileTransfert method like so</p>
  
  <pre><code>        var options = new FileUploadOptions();
          options.fileKey="file";
          options.mimeType="image/jpeg";
          //options.chunkedMode = true;
  
          var params = new Object();
          params.title = title;
          params.content = content;
          params.groupId = groupId;
  
          options.params = params;
  
          var ft = new FileTransfer();
          app.loadmask.show();
          ft.upload(app.imageURI, app.stores.actionAjaxURL + "&amp;cmd=addActualite", this.onSuccessCreateActualite, this.onFailureCreateActualite, options, true);
  </code></pre>
  
  <p>This goes to the success callback function which is :</p>
  
  <pre><code>onSuccessCreateActualite: function(response, options) {
          /* REINIT FORM VALUES */
          app.imageURI = null;
          console.log("This log appears");
          this.titleField.reset();
          console.log("This log does not appear");
          this.groupSelect.reset();
          this.contentField.reset();
          this.addBtn.resumeEvents();
          this.picturePnl.update("No Picture");
  
          app.stores.actualites.load();
          app.loadmask.hide();
          app.views.viewport.actualites.setActiveItem(
              app.views.viewport.actualites.actualitesList, {type:'slide', direction:'right'}
          );
  
          app.views.viewport.actualites.actualitesList.actuGrid.scroller.scrollTo({ x: 0, y: 0 });
  },
  </code></pre>
  
  <p>And I'm getting this error :</p>
  
  <p><strong>Error in success callback: com.phonegap.filetransfer1 = TypeError: 'undefined' is not an object</strong></p>
  
  <p>Does anyone knows why ?</p>
  
  <p>Thanks</p>
