我在更新期间提交时收到错误脱水属性值错误.我搜索了它看起来和NHibernate类似:错误脱水属性 - 这到底是什么？唯一的区别是,在提到的问题中,NHibernate抱怨无法解决财产问题

以下是详细错误.

Test 'Tests.Services.StickerInvoiceServiceTests.update_sticker_info_succeeds' failed:

我已阅读所有帖子并知道IndexOutOfRange通常会发生,因为列被引用了两次.但我根据我的映射看不出这是怎么回事.如果配置中的SHOW_SQL为true,我会看到Events表中的Insert ,然后IndexOutOfRangeException是RadioButtonQuestions表引用的表.我看不到它试图使用的SQL会产生异常.我尝试使用AutoMapping,现在已经切换到ClassMap这两个类的完全,以尝试缩小问题范围.

}

public class Event : Entity
{
    [Required]
    public virtual string Title { get; set; }

    [Required]
    public virtual DateTime EventDate { get; set; }

    public virtual IList<RadioButtonQuestions> RadioButtonQuestions { get; protected internal set; }
}




public class RadioButtonQuestionMap : ClassMap<RadioButtonQuestion>
{
    public RadioButtonQuestionMap() …
