Digging through this a bit deeper, there is an interaction going on here with
tapestry-security.
When the session expires, the user is no longer logged in, and thus
ajax call is being redirected to a login screen, thus the exceptions.
But the problem still remains the same, there seems to be no good way
to redirect the page to itself when the Grid does inPlace update,
and the session is no longer available.
Any more thoughts/ideas?
