We recently upgraded our web site to tapestry 4 and we've been experiencing several ConcurrentModificationException on the visit object lately (because of a form focus issue :-\)... Has anyone tried to write a WebRequestFilter that would serialize requests from the same session instead of allowing them to execute concurrently? I have in place a servletfilter for that but it doesn't seem to work well... and the framework should be able to handle that since it is recognising the same session (and provides the same visit object...)
Thanks, Henri.
