       //Session["storedevices"] //Session is null/lost here?
       //to do

There's something strange going on with your code. It should work just fine.

Some things to help you to debug:

• Make sure you are not trying to access Session["storedevices"] on the BaseController before the Controller.Session property is actually populated. For instance, it's supposed to be null on the Controller's constructor. It's only available after the Initialize method, if I can remember well.
• Make sure this.Session == base.Session . For some reason, you might be "newing" the Session property in the descendant Controller. Just put a breakpoint there and make sure this expression is true.
• Make sure this.Session == System.Web.HttpContext.Current.Session both in the descendant Controller and in the base Controller.
