function webfm_attach_attached_form($node) {
  $form['#theme'] = 'webfm_attach_attached_form';

  // This form input (id = edit-attachlist) will hold the comma-separated
  // ordered list of attached fids. We need to store the attachments (which
  // might not yet been saved to the database) in two cases:
  // 1) A form_validate fails when trying to save/preview. The form is not
  //    rebuild by form_alter, but form values are refilled. #value => '' would
  //    delete the attachlist collected so far, so use #default_value => '' instead.
  $form['new']['attachlist'] = array(
    '#type' => 'hidden',
    '#default_value' => '',
  );

  // 2) If form_validate didn't fail, the form is rebuild with form_alter
  //    and the value is reset. But we have the list in the POST parameters.
  //    Use default_value here, too, so that it can still be changed if we get
  //    a form_validate error *after* a successful preview.
  if ($_POST['attachlist']) {
    $form['new']['attachlist']['#default_value'] = $_POST['attachlist'];
  }
  return $form;
