Error using Autofac.Extras.NHibernate - nhibernate

Question

I'm trying to inject dependencies im my models that NHibernate creates.
What I'm trying to do is the same here: http://fabiomaulo.blogspot.com.br/2008/11/entities-behavior-injection.html
But my container is Autofac.
So, I've found https://www.nuget.org/packages/Autofac.Extras.NHibernate/
I saw the post http://chadly.net/2009/05/dependency-injection-with-nhibernate-and-autofac/ that I've think is the origin of the Autofac.Extras.NHibernate.
My problem is that the code in Autofac.Extras.NHibernate and described in Chad post are different.
Looking at the source code I (think) figured out how to set the BytecodeProvider using:
Cfg.Environment.BytecodeProvider = new AutofacBytecodeProvider(Container, new DefaultProxyFactoryFactory(), new DefaultCollectionTypeFactory());
But now, I'm getting an exception when I tried to retrieve data from database:
[PropertyAccessException: could not set a property value by reflection setter of NHibernate.Autofac2.App_Start.Model.User.Id]
If I comment the line where I set BytecodeProvider the code works.
I created a POC to simulate:
My model:
public class User
{
private readonly ISomeService _someService;
public User(ISomeService someService)
{
this._someService = someService;
}
public virtual long Id { get; set; }
public virtual string Name { get; set; }
public virtual string GetTranslate
{
get { return this._someService != null ? this._someService.T(this.Name) : " No Translate" + this.Name; }
}
}
My mapping:
public class UserMap : ClassMap<User>
{
public UserMap()
{
Id(x => x.Id);
Map(x => x.Name)
.Length(16)
.Not.Nullable();
}
}
Creation of the Autofac container and SessionFactory using Fluent Nhibernate:
// Create your builder.
var builder = new ContainerBuilder();
builder.RegisterType<SomeService>().As<ISomeService>();
builder.RegisterType<User>().As<IUser>();
Container = builder.Build();
SessionFactory = Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2005.ConnectionString("Data Source=(local);Initial Catalog=NHibernate.Autofac;User ID=test;Password=102030;Pooling=True"))
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<MvcApplication>())
.ExposeConfiguration(config => config.Properties.Add("use_proxy_validator", "false"))
.ExposeConfiguration(config =>
{
//config.Properties.Add("proxyfactory.factory_class", "");
Cfg.Environment.BytecodeProvider = new AutofacBytecodeProvider(Container, new DefaultProxyFactoryFactory(), new DefaultCollectionTypeFactory());
new SchemaExport(config).Drop(false, false);
new SchemaExport(config).Create(false, true);
})
.BuildSessionFactory();

Well, I've found a solution that works for me.
Now, I'm using NHibernate.DependencyInjection.
The IEntityInjector implemenation:
public class EntityInjector : IEntityInjector
{
private readonly IContainer _container;
public EntityInjector(IContainer container)
{
_container = container;
}
public object[] GetConstructorParameters(System.Type type)
{
var constructor = type.GetConstructors().FirstOrDefault();
if (constructor != null)
return constructor.GetParameters().Select(a => a.ParameterType).Select(b => this._container.Resolve(b)).ToArray();
return null;
}
}
And in Global.asax:
Initializer.RegisterBytecodeProvider(new EntityInjector(Container));
SessionFactory = Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2005.ConnectionString("Data Source=(local);Initial Catalog=NHibernate.Autofac;User ID=XXX;Password=XXXX;Pooling=True"))
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<MvcApplication>())
.ExposeConfiguration(config => config.Properties.Add("use_proxy_validator", "false"))
.ExposeConfiguration(config =>
{
new SchemaExport(config).Drop(false, false);
new SchemaExport(config).Create(false, true);
})
.BuildSessionFactory();
