ArgumentOutOfRangeException: index was out of range

Question

I get this weird ArgumentOutOfRangeException whenever I use the PersitenceSpecification Class to validate an object that has a reference to an object of value.

    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 class CatalogItemMapping : ClassMap<CatalogItem>
    {
        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"));
        }
    }

    [TestFixture]
    public class When_verifying_the_class_mapping_of_a_catalog_item
        : NHibernateSpecification
    {
        [Test]
        public void Then_a_catalog_object_should_be_persistable()
        {
            new PersistenceSpecification<CatalogItem>(Session)
                .VerifyTheMappings();
        }
    }

    [TestFixture]
    public class NHibernateSpecification
        : Specification
    {
        protected ISession Session { get; private set; }

        protected override void Establish_context()
        {
            var configuration = new SQLiteConfiguration()
                .InMemory()
                .ShowSql()
                .ToProperties();

            var sessionSource = new SessionSource(configuration, new
RetailerPersistenceModel());
            Session = sessionSource.CreateSession();

            sessionSource.BuildSchema(Session);
            ProvideInitialData(Session);

            Session.Flush();
            Session.Clear();
        }

        protected override void Dispose_context()
        {
            Session.Dispose();
            Session = null;
        }

        protected virtual void ProvideInitialData(ISession session)
        {}
    }

Here is the error I get:

Answer 5

In my specific case, I added a property, as well as an identifier (using attributes) over the same .NET property. This led to the same error.

Answer 6

An old question, but if someone encounters the same problem as me, it can help to find out that this problem with Fluent Nhibernate (ColumnPrefix applies only to the first component display inside the ComponentMap) may give the same exception, since column prefixes do not always apply.
