sulu extend PageDocument

Question

我想擴展PageDocument類。我添加以下設置來我app/config/config.yml

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

類Client\Bundle\WebsiteBundle\Document\PageDocument只是擴展了類Sulu\Bundle\ContentBundle\Document\PageDocument

namespace Client\Bundle\WebsiteBundle\Document; 

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

class PageDocument extends BasePageDocument 
{ 
} 

打開在前端的作品頁面，但是編輯在後臺頁面拋出以下錯誤消息預覽區域：

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

恐怕要告訴你，這種行爲是一個錯誤......我可以跟蹤下來了一點，創造了一個issue on GitHub，你可以在那裏跟蹤進一步的進展。

但是，此錯誤僅影響預覽，而不影響系統的其他部分。
