Code

function get_flag() {

  // Backward compatibility: There may exist old views on the system whose
  // 'flag' option isn't set. (This happens if the admin had skippped
  // clicking the 'Update' button.) When run, these views should behave as
  // if the first flag was selected.
  if (!isset($this->options['flag'])) {

      ->get_flag_type());
  }

  // Validation: Since validate() is called only when in Views's
  // administrative UI, we need to do validation at "run time" ourselves.

      drupal_set_message($error, 'error');
