Hi, Ken
May be it possible but will be hard to achieve, because T5 (you use T5,
don't you?) use hidden fields with internal information with every form.
Without this information form can't be processed.
As for your stacktrace:
You try to change character encoding for request when it is too late for
this. If you do this as RequestHandler it should be placed first in
chain. But probably usage of javax.servlet.ServletFilter is more
appropriated.
