ok, finally got this working with 2 changes.
1. DefaultEngineContextFactory.ResolveRequestSession now returns a new
Session Adapter instead of null.
2. my dependency resolver is now implemented like this
public object Resolve(CreationContext context,
ISubDependencyResolver contextHandlerResolver, ComponentModel model,
DependencyModel dependency)
{
var factory = new MonoRailHttpHandlerFactory();
var http_context = HttpContext.Current;
var request = http_context.Request;
var url_info = factory.UrlTokenizer.TokenizeUrl
(request.FilePath, request.PathInfo, request.Url, request.IsLocal,
request.ApplicationPath);
return factory.EngineContextFactory.Create
(factory.Container, url_info, http_context, new RouteMatch());
}
I think the problem is that
MonoRailHttpHandlerFactory.CurrentEngineContext is just pulling the
engine from the Items collection and this was created prior to session
being initialized. or it hasn't been initialized yet, and GetHandler
wasn't called so the context and related objects haven't been created.
by creating a new engine context it's now working as expected. here is
CanResolve
public bool CanResolve(CreationContext context,
ISubDependencyResolver contextHandlerResolver, ComponentModel model,
DependencyModel dependency)
{
if (model.Service != typeof(IUserStartUp)) return false;
return dependency.TargetType == typeof (IEngineContext);
}
as you can see I'm only using this for one class at this point, so
this won't affect my controllers.
