NHibernate的：错误脱水性能 - 到底这是什么道理？ [英] NHibernate: Error dehydrating property - What the heck is this?

问题描述

我在一家金融系统做一个相当复杂的NHibernate的交易，创建付款，记录台账项，检查，看看是否付款的发票的总金额，如果是的话标志着发票全额支付，等等......很多有趣的东西。 。当然它有一个单一的事务中发生

当我尝试提交更改的会议上，我得到以下错误：

 为C3.DataModel.CFAPTransaction.Vendor 
错误脱水的属性值 

谷歌搜索这个不转了许多纪录。谁能告诉我这是什么意思，并在那里我需要专注我的调试工作？

更新

每请求，以下是完整的错误消息：

它不会出现在查询数据库时这正在发生。我有一种感觉它有问题，我创建了一堆的对象，有关它们，然后试着坚持他们，但是这是一个纯粹的猜测。

解决方案

这可能是NHibernate的不示值误差的正确的属性，检查相邻的属性在映射文件中，从您的数据库和数据类型在性能.NET或重复列中的数据类型之间的关系，寻找错误......还要检查该链接功能NHibernate - IndexOutOfRange

I'm doing a fairly complex NHibernate transaction in a financial system, creating a payment, recording the ledger entries, checking to see if the payment is the total amount of an invoice, if so marking the invoice as paid in full, etc... lots of fun stuff. Naturally it has to happen inside a single transaction.

When I try to commit the change to the session, I get the following error:

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

Googling this did not turn up many record. Can someone tell me what this means and where I need to focus my debugging efforts?

UPDATE

Per request, here is the full error message:

It does not appear this is occurring when querying the database. I have a feeling it has problems with me creating a bunch of objects, relating them, and then trying to persist them, but that's a pure guess.

解决方案

It's likely that nhibernate is not showing the correct property of error, check the adjacent properties in the mapping file, looking for errors in relationship between data types from your database and data types from .net or repeated columns in properties... also check this link Fluent NHibernate - IndexOutOfRange
