NHibernate:错误脱水属性 - 这到底是什么？

Question

我正在金融系统中进行相当复杂的NHibernate交易,创建付款,记录分类帐条目,检查付款是否是发票的总金额,如果是,则将发票标记为全额付款等.很多有趣的东西.当然,它必须在单个交易中发生.

当我尝试将更改提交到会话时,我收到以下错误:

Error dehydrating property value for C3.DataModel.CFAPTransaction.Vendor

谷歌搜索这并没有出现很多记录.有人能告诉我这意味着什么以及我需要在哪里集中调试工作？

UPDATE

每个请求,这是完整的错误消息:

更新将 NHibernate抛入DEBUG模式,我得到了一堆这样的东西:

查询数据库时似乎没有出现这种情况.我有一种感觉,我创建一堆对象,关联它们,然后试图坚持它们有问题,但这是一个纯粹的猜测.

nhibernate可能没有显示错误的正确属性,检查映射文件中的相邻属性,查找数据库中数据类型与.net中的数据类型或属性中重复列之间的关系中的错误...也检查这个链接Fluent NHibernate - IndexOutOfRange
