I do the following:

    var @case = new Case
    {
        Name = "test"
    };

    // User is persistent and loaded in the same session
    User.AddCase(@case); // sets @case.User = User too
    Session.Update(User);

    response.CaseId = @case.Id;

The cascade on User.Cases is set to All. But @case.Id is not set until the transaction is committed. Is that expected behavior? I would very much like to get the Id before committing. Can it be done?
