Code

function _hierarchical_select_add_js_settings($settings, &$form_state) {
  global $views_ajax_form_js_settings;

  // If we're on a Views-powered form, we must use $form_state['js settings'].
  if (isset($form_state['view']) && isset($form_state['ajax']) && !empty($form_state['ajax'])) {
    $form_state['js settings'] = !isset($form_state['js settings']) || !is_array($form_state['js settings']) ? array() : $form_state['js settings'];
    $form_state['js settings'] = array_merge_recursive($form_state['js settings'], $settings);
  }
  else {
