更新：很确定这是一个错误，在 Jira 上提出了问题：http ://bit.ly/gpstW9
更新（2011 年 5 月 5 日）：根据 jwage 的建议，我已切换到类别和帖子之间的引用关系（而不是嵌入）。
我正在使用最新版本的 Doctrine ODM（来自 Git 的新版本）。
我有三个级别的文档（两个嵌入）；类别 -> EmbedsMany：帖子 -> EmbedsMany PostVersion。
PostVersion 由 Post 自动处理。当我发布新帖子时，它实际上也在后台创建了一个新的 PostVersion。
我的问题是 Doctrine 与 PostVersions 混淆，如果我检索现有类别并向其添加新帖子，则新帖子的 PostVersions 将添加到类别 $posts 集合中的第一个帖子。
一步步：
- 创建新帖子 (Post1) 和类别
- 将 Post1 添加到类别
- 保持类别、刷新、清除
- 检索类别
- 发新帖 (Post2)
- 将 Post2 添加到类别
- 冲洗
在这个阶段的数据库中，应该有一个 Category，两个 Post，每个 Post 有一个 PostVersion。然而，实际发生的是一个类别，两个帖子，第一个帖子有两个 PostVersions，第二个帖子有零个 PostVersions。
请求期间的文档本身是正确的，只是希望将其持久化到错误的数据库中。我错过了什么？
