Thanks Igor for the quick response - I guess this is stating the obvious, but
I conclude that this is just part of the page/component serialization?
Correct me if I am wrong, but from what I understand the reference to an
outer scope obj. is a 'field' of the inner class and therefore required to
be serializable by wicket.
