Php sulu扩展页面文档

我正在尝试扩展PageDocument类。我将以下设置添加到我的

app/config/config.yml

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
{
}

在前端打开页面可以工作，但在后端编辑页面会在预览区域显示以下错误消息：

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

我恐怕要告诉你，这种行为是一个bug……我可以找到它并创建一个，你可以在那里跟踪进一步的进展

但是，此错误只影响预览，而不影响系统的其余部分。

您不能命名引发的异常吗？有一些组件处理元数据，根据错误文本很难判断是哪个组件出现问题。添加了异常名称和堆栈跟踪。希望这对您有所帮助。
