我正在使用nHibernate无状态会话来获取对象,更新一个属性并将对象保存回数据库.

我一直收到错误消息:

无状态会话无法获取代理

我有类似的代码在其他地方工作,所以我无法弄清楚为什么这不起作用.有谁知道问题可能是什么？

我正在尝试更新该ScreenLockVersion属性.

制图:

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                  assembly="ApplicationUtilities"
                  namespace="ApplicationUtilities.Concurrency">
  <class name="Screen" table="concurrency_screen" dynamic-update="true" optimistic-lock="all">
    <id name="ID" column="screenID">
      <generator class="identity" />
    </id>
    <property name="ScreenName" column="screenName" />
    <property name="SubScreenName" column="subScreenName" />
    <property name="ScreenLockID" column="screenLockID" />
    <property name="ScreenLockVersion" column="screenLockVersion" />
