ninject 2 and db4o - asp.net-mvc

Question

I am trying to use ninject with db4o and I have a problem. This is the relevant code from the Global.aspx
static IObjectServer _server;
protected override void OnApplicationStarted()
{
AutoMapperConfiguration.Configure();
RegisterRoutes(RouteTable.Routes);
RegisterAllControllersIn(Assembly.GetExecutingAssembly());
if (_server == null)
{
// opening a server for a client/server session
IServerConfiguration serverConfiguration = Db4oClientServer.NewServerConfiguration();
serverConfiguration.File.Storage = new MemoryStorage();
_server = Db4oClientServer.OpenServer(serverConfiguration, "myServerDb.db4o", 0);
}
}
public static IObjectContainer OpenClient()
{
return _server.OpenClient();
}
public MvcApplication()
{
this.EndRequest += MvcApplication_EndRequest;
}
private void MvcApplication_EndRequest(object sender, System.EventArgs e)
{
if (Context.Items.Contains(ServiceModule.SESSION_KEY))
{
IObjectContainer Session = (IObjectContainer)Context.Items[ServiceModule.SESSION_KEY];
Session.Close();
Session.Dispose();
Context.Items[ServiceModule.SESSION_KEY] = null;
}
}
protected override IKernel CreateKernel()
{
return new StandardKernel(new ServiceModule());
}
public override void OnApplicationEnded()
{
_server.Close();
}
and this is the code in ServiceModule
internal const string SESSION_KEY = "Db4o.IObjectServer";
public override void Load()
{
Bind<IObjectContainer>().ToMethod(x => GetRequestObjectContainer(x)).InRequestScope();
Bind<ISession>().To<Db4oSession>();
}
private IObjectContainer GetRequestObjectContainer(IContext Ctx)
{
IDictionary Dict = HttpContext.Current.Items;
IObjectContainer container;
if (!Dict.Contains(SESSION_KEY))
{
container = MvcApplication.OpenClient();
Dict.Add(SESSION_KEY, container);
}
else
{
container = (IObjectContainer)Dict[SESSION_KEY];
}
return container;
}
I then try to inject it into my session as such:
public Db4oSession(IObjectContainer client)
{
db = client;
}
however, after the first call, the client is always closed - as it should be because of the code in MvcApplication_EndRequest. The problem is that the code in GetRequestObjectContainer is only ever called once. What am I doing wrong?
Also, MvcApplication_EndRequest is always called 3 times, is this normal?
Thanks!

This seems to have done the trick... add InRequestScope to the other injection:
Bind<ISession>().To<Db4oSession>().InRequestScope();
