On NH 4.0.2, this works perfectly:
public class Sample
{
public int Id { get; set; }
public int? RowVersion { get; set; }
public string Name { get; set; }
}
var mapper = new ModelMapper();
mapper.Class<Sample>(x =>
{
x.Table("sample");
x.Id(y => y.Id, y => y.Generator(Generators.Identity));
x.Version(y => y.RowVersion, y => y.UnsavedValue(null));
x.Property(y => y.Name);
});
cfg.AddMapping(mapper.CompileMappingForAllExplicitlyAddedEntities());
session.Save(new Sample {Name = "ABC"});
session.Flush();
session.Query<Sample>().ToList();
And also this:
x.Version(y => y.RowVersion, y => y.UnsavedValue(-1));
session.Save(new Sample { Name = "ABC", RowVersion = -1 });
So, I'd say it's something in your code.
