我创建了一个新的Movie ContentType，其中附加了Taxonomy Field（使用迁移）。使用IEventHandler Enabled事件创建分类标准名称和术语。
我登录仪表板，我可以看到使用所有术语创建的分类法字段。
现在，我尝试创建一个新的Movie ContentItem，我得到以下异常。
请问好吗？

2014-02-27 13:44:39,054 [24] NHibernate.AssertionFailure - An AssertionFailure occurred - this may indicate a bug in NHibernate or in your custom types.
NHibernate.AssertionFailure: null id in Orchard.ContentManagement.Records.ContentItemRecord entry (don't flush the Session after an exception occurs)
答案 0 :(得分：1)
正如写here，这意味着发生了一些错误，NHibernate无法保存记录并为其创建id，但半持久保存记录并尝试再次保存...没有{{1 }}。基础错误各不相同，可能是由于你的情况下缺少表，列名中的拼写错误，模型和迁移之间的任何不一致（在Orchard或类似的框架中 - 我有一些可空/不可错的不匹配）使用保留字，a独特的约束......没有防弹解决方案，你必须找到（调试软件是必须的并记录你的朋友）并解决原因。
