I'm already passing my objects as parameters to asynch method and it works great. The problem begins when I want to render mail using Renderer.render method because my objects are not within conversation context of renderer. And in my email template I need to access my user object to get his address, name etc.. That's why I was trying to programatically set these inside of asynch method just before calling renderer, unfotunetly I keep getting NPE.
