Code

function show_build_group_form(&$form, &$form_state) {
  if (empty($this->options['is_grouped'])) {
    return;
  }

  $this->build_group_form($form, $form_state);

  // When we click the expose button, we add new gadgets to the form but they
  // have no data in $_POST so their defaults get wiped out. This prevents
  // these defaults from getting wiped out. This setting will only be TRUE
  // during a 2nd pass rerender.
  if (!empty($form_state['force_build_group_options'])) {
    foreach (element_children($form['group_info']) as $id) {
      if (isset($form['group_info'][$id]['#default_value']) && !isset($form['group_info'][$id]['#value'])) {
        $form['group_info'][$id]['#value'] = $form['group_info'][$id]['#default_value'];
      }
