AclExtras警告錯誤

Question

在CakePHP 2 book/Acl Tutorial/Part 2，我執行命令：

./Console/cake AclExtras.AclExtras aco_sync 

，我得到一個警告錯誤：

Warning Error: Argument 1 passed to Component::startup() must be an instance of Controller, 
null given, called in 
/opt/lampp/htdocs/acl/app/Plugin/AclExtras/Console/Command/AclExtrasShell.php 
on line 80 and defined in [/opt/lampp/htdocs/acl/lib/Cake/Controller/Component.php, line 119] 

的ACOS表獲取與NULL填充在model場NULL在所有foreign_key的字段。

我該如何解決這個錯誤？

感謝

，請更改開機功能：

public function startup() { 
    parent::startup(); 
    $controller = new Controller(); 
    $collection = new ComponentCollection(); 
    $this->Acl = new AclComponent($collection); 
    $this->Acl->startup($controller); 
    $this->Aco = $this->Acl->Aco; 
}
