每当我使用PersitenceSpecification类来验证具有对值对象的引用的实体时,我就会得到这个奇怪的ArgumentOutOfRangeException.

    public class CatalogItem : DomainEntity
    {
        internal virtual Manufacturer Manufacturer { get; private
set; }
        internal virtual String Name { get; private set; }

        protected CatalogItem()
        {}

        public CatalogItem(String name, String manufacturer)
        {
            Name = name;
            Manufacturer = new Manufacturer(manufacturer);

    {
        public CatalogItemMapping()
        {
            Id(catalogItem => catalogItem.Id);

            Component<Manufacturer>(category => category.Manufacturer,
                                    m => m.Map(manufacturer =>
manufacturer.Name));

            Map(catalogItem => catalogItem.Name);
            Map(Reveal.Property<CatalogItem>("Price"));
        }
    }
