  // Parameters for token_replace().
  $data = array();
  $options = array('clear' => TRUE);

  if ($entity = $this->entity) {
    // For new entities, entity and revision id are not set. This leads to
    // * token replacement emitting PHP warnings
    // * views choking on empty arguments
    // We workaround this by filling in '0' for these IDs
    // and use a clone to leave no traces of our unholy doings.
    $info = entity_get_info($this->instance['entity_type']);

  }
  // Replace tokens for each argument.
  foreach ($args as $key => $arg) {
