    <p>I am trying to use ninject with db4o and I have a problem. This is the relevant code from the Global.aspx</p> <pre><code> 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(); } </code></pre> <p>and this is the code in ServiceModule</p> <pre><code> internal const string SESSION_KEY = "Db4o.IObjectServer"; public override void Load() { Bind&lt;IObjectContainer&gt;().ToMethod(x =&gt; GetRequestObjectContainer(x)).InRequestScope(); Bind&lt;ISession&gt;().To&lt;Db4oSession&gt;(); } 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; } </code></pre> <p>I then try to inject it into my session as such:</p> <pre><code> public Db4oSession(IObjectContainer client) { db = client; } </code></pre> <p>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?</p> <p>Also, MvcApplication_EndRequest is always called 3 times, is this normal?</p> <p>Thanks!</p>

    1. CO`MvcApplication_EndRequest` is probably called three times because of a request to `favicon.ico` and `site.css` when using a default mvc2 template? Look at the request path to make sure.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
