We're still having issues with our reverse proxy. This doesn't even involve
the redirect issue yet. When our form hits user-defined validation errors
we pass messages back to the feedback panel an then do nothing (so the
default behavior kicks in to send it back to the form page). But the url it
comes up with to return to the page is bogus. The wicket logs output:
DEBUG 2007-06-07 10:54:38,378 http.WebResponse (redirect:196) - Redirecting
to ?wicket:interface=:0::::
which is just the query string. Am I missing some major configuration
parameter? Or is the default behavior just not doing the right thing?
Thanks.
