php – Joomla中的后端操作不起作用

未捕获的TypeError：无法读取未定义的属性“任务”(在chrome中)
TypeError：b未定义(以ff为单位)

我的代码是：

view.html.php

<?// no direct access

defined( '_JEXEC' ) or die( 'Restricted access' );

jimport( 'joomla.application.component.view');


class ObshViewObsh extends JView
{

    function display($tpl = null)
    {

        $task = JRequest::getVar('task','');
        switch($task){            
            case 'config': $this->config();break;
            default: $this->windows();
        }

        parent::display($tpl);
    }

    function windows(){
        JToolBarHelper::title( JText::_( 'Общежития' ),'generic.png' ); 
        JToolBarHelper::custom('config','options','','Настройки',false); //<<< --- this link doesn't work

    }

     function config(){
        JToolBarHelper::title( JText::_( 'Общежития - настройка компонента' ),'generic.png' );
        JToolBarHelper::apply('edit_config');
        JToolBarHelper::cancel('cancel');    
    }          

}

Controller.php这样

<?php
 error_reporting(E_ALL);
// No direct access

defined( '_JEXEC' ) or die( 'Restricted access' );

jimport('joomla.application.component.controller');


class ObshController extends JController
{       

    function config(){
        JRequest::setVar( 'view','obsh' );
        JRequest::setVar( 'layout','config'  );
        JRequest::setVar( 'hidemainmenu',1 );
        parent::display();
    }        
}
