  // Get the cached form.
  $form_state = array(
    'storage' => NULL,
    'submitted' => FALSE,

      'data' => '',
    ));
    exit;
  }

  // Set the form state values.
  $form_state = array_merge($form_state, array(
    'values' => $_POST,
  ));

  // Set the new form rrule value.
  $form[$field_name]['rrule']['#value'] = $form_state['values'][$field_name]['rrule'];
