File is not uploading

I've found, that the file is not uploading. Module not creating preview, just doing nothing visible.
I had such issue in imagefield plugin for CCK, so I tried this one here too. And it solves the issue. Here it is.

filefield.module line 338:

before

    case 'form':
      $form = _filefield_widget_form($node, $field, $node_field);
      return $form;

after

    case 'form':
      if (is_array($_SESSION['filefield'][$fieldname]) && count($_SESSION['filefield'][$fieldname])) {
        foreach($_SESSION['filefield'][$fieldname] as $delta => $file) {
          $node_field[] = $file;
        }
      }     
      $form = _filefield_widget_form($node, $field, $node_field);
      return $form;
