Php Joomla 3.5子控制器/类

我在joomla 3.5中遇到问题，无法在分包商中找到任务。我在跑J！转储，可以看到它正在运行分包商的构造函数，但是

/administrator/index.php？option=com\u mycomponent&task=subctrl.trask

返回

task[trask]not found

我尝试在构造函数中使用

$this->registerTask（'trask'，trask'）

。。。你知道我做错了什么吗

/管理员/components/com_mycomponent/controllers/subctrl.php

以下是callstack中引用的管理部分

mycomponent.php

文件（为了清晰起见，删除了一些注释行）：

---

我认为您无法从
JControllerAdmin
进行扩展。您应该从
jcontrolleregacy
或
jcontrolleregacy
进行扩展

<?php
defined('_JEXEC') or die ;
class MycomponentControllerSubctrl extends JControllerAdmin
{
    function __construct()
    {
        $this->registerTask('trask', 'trask');
        dumpMessage('running controller');
        dump($this, 'Ctrler');
    }

    public function trask()
    {
        dumpMessage('running Ctrl Trask');
        return true;
    }
}
