Code

public function getInfo() {
  // By default, we don't want Ajax commands being rendered in the context of
  // an HTML page, so we don't provide defaults for #theme or #theme_wrappers.
  // However, modules can set these properties (for example, to provide an
  // HTML debugging page that displays rather than executes Ajax commands).

    '#header' => TRUE,
    '#commands' => array(),
    '#error' => NULL,
