该插件不允许使用控制器

我尝试添加一个新的控制器，它有一个名为confirmAgbAction的动作。

<?php
namespace Eddcapone'MyExtension'Controller;
/**
 * CustomController
 */
class CustomController extends 'TYPO3'CMS'Extbase'Mvc'Controller'ActionController 
{
    /**
     * action list
     *
     * @return void
     */
    public function confirmAgbAction()
    {
        echo "<p>HALLO WELT</p>";    
    }
}

我甚至把它添加到ext_localconf.php

<?php
if (!defined('TYPO3_MODE')) {
    die('Access denied.');
}
'TYPO3'CMS'Extbase'Utility'ExtensionUtility::configurePlugin(
    'Eddcapone.' . $_EXTKEY,
    'Myfilelist',
    array(
        'Category' => 'list,show',
        'File' => 'show',
        'Download' => 'download',
        'Custom' => 'confirmAgb'
    ),
    // non-cacheable actions
    array(
        'Category' => 'list,show',
        'File' => 'topFive',
        'Download' => 'download',
        'Custom' => 'confirmAgb'
    )
);

这是我在模板中调用动作的方式:

<f:link.action controller="Custom" action="confirmAgb" pluginName="Myfilelist" class="mbButton">Download</f:link.action>

然而，我总是得到:

#1313855173: The controller "Custom" is not allowed by this plugin. Please check for TYPO3'CMS'Extbase'Utility'ExtensionUtility::configurePlugin() in your ext_localconf.php.
