Hey Uli & others,
I dug up this old thread as I run into the same issue myself with
T5.1. Did you ever manage to solve this in a satisfactory way? It's
clear that the issue is the same - requestGlobals.getRequest() returns
null since I'm contributing my handler before everything else but I
also want to create a sessionstate object. It's entirely possible that
things have changed since and I simply should be contributing my
handler right after the handler (if so, named what?) that stores the
request globals objects but I didn't check yet. Is there any better
workaround than Thiago's httpSession.set("aso:" +
User.class.getName(), user)?
