[castle][JIRA] Created: (MR-445) Component Resolution Occurs before Session is Acquired

Key: MR-445
URL: http://support.castleproject.org//browse/MR-445
Project: MonoRail
Issue Type: Improvement
Components: Core
Affects Versions: Release Candidate 3
Reporter: João Bragança
In http://forum.castleproject.org/viewtopic.php?p=9850, herny says 'Probably due the cache implementation, the controller is now instanced before the session acquire step.'
I understand this is performance reasons. However I would like to implement a PerSessionLifestyleManager similar to the PerWebRequest.

--------------------------------
I, too, had implemented a PerSessionLifestyleManager that worked in WebForms apps, but not in monorail, so +1 for this issue. As of now, I cannot inject components into my controllers that have session scope.
At the moment, my work-around is, instead of injecting the session scoped objects, to inject a transient or request scoped components that acts like a simple service provider and factory that caches the objects in session scope. However, it is by far not as nice as it could be compared to directly injected dependencies.

---------------------------------------
I guess you're referring to the fact that the controller is created by the MRHttpHandlerFactory and as a consequence all its dependencies are resolved before a session is made available. Unfortunately that's unlikely to change. That factory needs to return different handlers based on request information.
What you could do is to proxy the per session components, and resolve them (from the session) lazily.

Resolution: Won't Fix
This is a consequence of the MR design, and it's unlikely to change
