NHibernate级联SaveUpdate

我在通过在我的实体上级联saveupdate保存关联方面存在问题。我有这个映射覆盖，并想通过级联保存它的一对多关联，但这是行不通的。NHibernate级联SaveUpdate

public class DomainMappingOverride : IAutoMappingOverride<Tcf.Domain.Entities.Domain> 
{ 
    /// <summary> 
    /// Overrides the specified mapping. 
    /// </summary> 
    /// <param name="mapping">The mapping.</param> 
    public void Override(AutoMapping<Tcf.Domain.Entities.Domain> mapping) 
    { 
     mapping.Table("domeinen"); 
     mapping.Map(m => m.Code, "code_1"); 
     mapping.Map(m => m.Description, "omschrijving"); 
     mapping.Map(m => m.Explanation, "toelichting"); 
     mapping.Map(m => m.CreatedBy, "createdby"); 
     mapping.Map(m => m.ModifiedBy, "modifiedby"); 
     mapping.Map(m => m.DateCreated, "createdat"); 
     mapping.Map(m => m.DateModified, "modifiedat"); 
     mapping.HasMany<SubDomain>(m => m.SubDomains).KeyColumn("domein").Cascade.SaveUpdate(); 
    } 
}

对象本身被保存，但不是关联，我做错了什么？
