sulu扩展PageDocument

Question

我正在尝试扩展PageDocument类。我将以下设置添加到我的app/config/config.yml中

sulu_document_manager:
    mapping:
        page:
            class: Client\Bundle\WebsiteBundle\Document\PageDocument
            phpcr_type: sulu:page

类Client\Bundle\WebsiteBundle\Document\PageDocument只是扩展了类Sulu\Bundle\ContentBundle\Document\PageDocument

namespace Client\Bundle\WebsiteBundle\Document;

use Sulu\Bundle\ContentBundle\Document\PageDocument as BasePageDocument;

class PageDocument extends BasePageDocument
{
}

在前端打开页面是可行的，但是在后端编辑页面会在预览区域引发以下错误消息：

Metadata with class "Sulu\Bundle\ContentBundle\Document\PageDocument" 
not found, known classes: "Client\Bundle\WebsiteBundle\Document
\PageDocument", "Sulu\Bundle\ContentBundle\Document\HomeDocument", 
"Sulu\Bundle\ContentBundle\Document\RouteDocument", "Sulu\Bundle
\SnippetBundle\Document\SnippetDocument", "Client\Bundle\WebsiteBundle
\Document\RegionDocument" 

500 Internal Server Error - MetadataNotFoundException

我不敢告诉你这种行为是错误的..。我可以跟踪它并创建一个关于GitHub的问题，您可以跟踪那里的进一步进展。

但是，此错误只影响预览，而不影响系统的其他部分。
