Can not load list actions on plugin if Class name was declared on Cake App?

[nguyentuandat]

When i commented as:

protected function _getControllers() {
        // Getting Cake controllers
        // Not use
        /*
        $objects = array('Cake' => array());
        $objects['Cake'] = App::objects('Controller');
        $unsetIndex = array_search("AppController", $objects['Cake']);
        if ($unsetIndex !== false) {
            unset($objects['Cake'][$unsetIndex]);
        }*/

        // App::objects does not return PagesController
        // Not use
        /*if (!in_array('PagesController', $objects['Cake'])) {
            array_unshift($objects['Cake'], 'PagesController');
        }
        */

It work fine for plugin.
