Session.removeAttribute is not working as expected

Posted a while back, am still struggling with the same issue. Really want to use ignite but am struggling to get this working correctly. What I'm noticing is that session.removeAttribute doesn't really remove the attribute, it only sets the value to null. I'm not sure if this is a setup issue
