Hi Ben -- What I am trying to do is preload some sample data, *as if* a user has entered it. So I want to have a Session object that I am going to programatically configure. Also I will be doing some background processing on behalf of a user so I will need to have a session object for that case as well. In neither case do I have a HttpRequest....

I hope that works for you, unfortunately I'm out of ideas on this one. I'm not sure what you're trying to do makes sense, if I understand this correctly. It sounds like you are trying to directly access a session-scoped ASO as your eager-loaded service gets created, correct? The problem is you aren't going to have a web session without an associated request from the user, which isn't going to be there at the point the Hivemind registry is created. In my case, I needed to eager-load a service that needed the asoManager, but I didn't actually pull any ASOs out of it until later while processing user requests. If you're trying to setup some initial state in each ASO as it is created, couldn't you add an initialize() method to the ASO class and create it using <invoke-factory>?

So I am going to try that. If anyone has a better idea let me know.
