To continue, the first one (probably; I'm still a
little fuzzy on OGNL sometimes) works because if a
property isn't found in the action it will continue
looking on the stack until it finds it or runs out.
Now, as to why #2 "doesn't work", I'm a little hazier
on that: perhaps when OGNL has an expression tree it
does lookup a bit differently or something?
