    <p>I'm having an issue with a closed, but not disposed NHibernate Session, inside Rhino Security. It looks like Windsor hands off the closed session to the AuthorizationService. The problem doesn't occur until the second call to the method below. The first call works fine. The Windsor container has everything configured for a Transient lifestyle.</p> <p>I'm using Sharp Architecture 2.0 RC.</p> <p>The calling service/task is handled by the same Windsor container as the AuthorizationRepository.</p> <p>Any thoughts as to what is causing the issue would be greatly appreciated?</p> <pre><code>namespace Rhino.Security.Services { public class AuthorizationRepository : IAuthorizationRepository { //... public virtual UsersGroup[] GetAssociatedUsersGroupFor(IUser user) { ICollection&lt;UsersGroup&gt; usersGroups = SecurityCriterions.AllGroups(user) .GetExecutableCriteria(session) //This session is closed and not connected when the line executes .AddOrder(Order.Asc("Name")) .SetCacheable(true) .List&lt;UsersGroup&gt;(); return usersGroups.ToArray(); //This line of code (ICollection...) throws the exception!!! } //... }} </code></pre> <p>The ISession Facility looks like the following:</p> <pre><code>container.AddFacility&lt;FactorySupportFacility&gt;() .Register(Component.For&lt;ISession&gt;() .UsingFactoryMethod(() =&gt; NHibernateSession.Current) .LifeStyle.Is(LifestyleType.Transient)); </code></pre> <p>The Rhino Security Component Registration looks like the following:</p> <pre><code>private static void AddRhinoSecurityComponentsTo(IWindsorContainer container) { // For RhinoSecurity container.Register( Component.For&lt;IAuthorizationService&gt;() .ImplementedBy&lt;AuthorizationService&gt;() .LifeStyle.Is(LifestyleType.Transient), Component.For&lt;IAuthorizationRepository&gt;() .ImplementedBy&lt;AuthorizationRepository&gt;() .LifeStyle.Is(LifestyleType.Transient), Component.For&lt;IPermissionsBuilderService&gt;() .ImplementedBy&lt;PermissionsBuilderService&gt;() .LifeStyle.Is(LifestyleType.Transient), Component.For&lt;IPermissionsService&gt;() .ImplementedBy&lt;PermissionsService&gt;() .LifeStyle.Is(LifestyleType.Transient) ); } </code></pre> <p>The method calling the AuthorizationService is one of the two following, depending:</p> <p>SecurityHelper(1):</p> <pre><code>public static bool IsAllowed(string operation) { User user = (User)HttpContext.Current.Session["User"]; IAuthorizationService authorizationService = ServiceLocator.Current.GetInstance&lt;IAuthorizationService&gt;(); return authorizationService.IsAllowed(user as User, operation); } </code></pre> <p>SecurityTasks(2):</p> <pre><code>public UsersGroup[] GetAssociatedUsersGroupFor(IUser user) { return authRepository.GetAssociatedUsersGroupFor(user); } </code></pre> <p>The NHibernate Init looks like the following:</p> <pre><code>NHibernateSession.Init( this.webSessionStorage, new[] { Server.MapPath("~/bin/ClinicalTrials.Infrastructure.dll") }, new AutoPersistenceModelGenerator().Generate(), Server.MapPath("~/NHibernate.config")); </code></pre> <p>The ysod looks like the following:</p> <pre><code>Session is closed!

    1. COI think this is an issue with the nHibernate lifestyle being transient everywhere. Any thoughts on how i could ensure that I never end up with a closed session referenced by Rhino Security?

    2. COIs there a way to ensure that only an open nHibernate session is passed along? Is there a way to register a component with windsor, so that it won't be given a disposed session?

    3. COCorrect, the lifestyle is the issue. You should be using session management around the web request. Follow the session per web request pattern for managing the NHibernate Session.

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.
