Hi,
exceptions are usually thrown with a reason - and the main reason why you
get so much in your log is that brix with wicket 6 isnt yet finished.
Especially the url-sharing part between brix and wicket is quite a problem
as brix relies on "full control" of the space while wickt 5 + 6 introduced
the concept of multiple url handlers - a concept brix itself never cared
for as it was created against 1.4 once and the traversal to wicket 5 and
wicket 6 never got finished yed. Especially the introduction of wicket 5
into brix is full of errors. I started to clear out many of them on the 6
branch, but hadn't enough time yet. Beside that I wanted to wait till
wicket 6 is released, as programming against dailies is problematic when
your low on time.
What brix currently needs is a logic similar to the SSL Url handler in
wicket 6, where requests go dont the flow while still the brix handler is
the "master" of these requests. I've done that on an experimental
base.
Best,
Kobinian
