使用INotifyPropertyChanged拦截器保存时出错

NHibernate & INotifyPropertyChanged ,存储库将返回实现INotifyPropertyChanged的代理集合,但在某些对象上保存或删除时将抛出错误:

   at NHibernate.Impl.SessionFactoryImpl.GetEntityPersister(String entityName)
   at NHibernate.Impl.SessionImpl.GetEntityPersister(String entityName, Object obj)
   at NHibernate.Engine.ForeignKeys.IsTransient(String entityName, Object entity, Nullable`1 assumed, ISessionImplementor session)
   at NHibernate.Event.Default.AbstractSaveEventListener.GetEntityState(Object entity, String entityName, EntityEntry entry, ISessionImplementor source)
   at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.PerformSaveOrUpdate(SaveOrUpdateEvent event)
   at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.OnSaveOrUpdate(SaveOrUpdateEvent event)
   at NHibernate.Impl.SessionImpl.FireSaveOrUpdate(SaveOrUpdateEvent event)
   at NHibernate.Impl.SessionImpl.SaveOrUpdate(Object obj)
   at MyCode ...

使用拦截器:

 public ISession GetSession(ISessionFactory factory)
        {
            IInterceptor dataBinding = new DataBindingInterceptor {SessionFactory = factory};
            return factory.OpenSession(dataBinding);
        }

没有

 public ISession GetSession(ISessionFactory factory)
        {
            return factory.OpenSession();
        }

我甚至弄不明白为什么拦截器会破坏保存。

我对代码所做的唯一更改就是更改了行

Type Type=Type.GetType(clazz);

到

public Type FindType(string typeName)
{
    foreach (Assembly assembly in AppDomain.CurrentDomain.GetAssemblies())
    {
        Type foundType = assembly.GetType(typeName);

        if (foundType != null)
            return foundType;
    }
    return null;
}
