Question

Nothing happens when updating an entity using the SaveOrUpdate method with FluentNHibernate. Flush does work but I want to use SaveOrUpdate due to existing repository infrastructure. What could be the problem?

Configuration:

sessionFactory = Fluently.Configure()
    .Database(MsSqlConfiguration
        .MsSql2005
            .ConnectionString(c => c.FromConnectionStringWithKey("repository")))
        .Mappings(m => m.FluentMappings
            .AddFromAssemblyOf<InvoiceMap>())
    .BuildSessionFactory();

Mappings:

public InvoiceMap()
{
    Id(x => x.InvoiceID, "InvoiceID");
    Map(x => x.InvoiceNumber);
    Map(x => x.InvoiceDate);
    Map(x => x.Company).CustomTypeIs<CompanyType>();
    Map(x => x.TransactionNumber).CustomTypeIs<TransactionNumberType>();
    Map(x => x.LongAddressBookNumber);
    Map(x => x.PurchaseOrderNumber);
    Map(x => x.ReceivedDateTime);
    Map(x => x.OCR);
    Map(x => x.DocumentNumber);
    Map(x => x.DocumentType);
    Map(x => x.PaymentStatus).CustomTypeIs<PaymentStatusType>();
    HasMany(x => x.Attestations)
        .KeyColumnNames.Add("InvoiceID")
        .Inverse()
        .Cascade.AllDeleteOrphan()
        .AsBag();
    HasMany(x => x.AttestationRequests)
        .KeyColumnNames.Add("InvoiceID")
        .Inverse()
        .Cascade.AllDeleteOrphan()
        .AsBag();
    HasMany(x => x.States)
        .KeyColumnNames.Add("InvoiceID")
        .Inverse()
        .Cascade.AllDeleteOrphan()
        .AsBag();
}

public AttestationMap()
{
    Id(x => x.ID, "AttestationID");
    Map(x => x.ReceivedAt);
    Map(x => x.IsInvalid, "Invalid");
    Map(x => x.InvalidationReason);
    Map(x => x.FileName);
    Map(x => x.FileData);
    References<EmployeeSnapshot>(x => x.Certifier, "Certifier")
        .Cascade.All()
        .FetchType.Join();
    References<Invoice>(x => x.Owner, "InvoiceID");
}

public AttestationReminderMap()
{
    Id(x => x.ID, "AttestationReminderID");
    Map(x => x.CC)
        .CustomTypeIs<RecipientType>();
    Map(x => x.Message);
    Map(x => x.SentAt);
    References<AttestationRequest>(x => x.Owner, "RequestID");
}

Any ideas?

Thanks,

When you say nothing happens, do you mean that nothing happens to the DB without a flush?

If so, that is expected behavior. Flush tells NHib to write the changes it has in memory to the DB.
