Heh, funnily enough I fixed the ? -> & problem earlier today and already committed it to CVS.
Right now there is no way to get rid of the conversationId parameter except by removing the SeamRedirectFilter from web.xml.
hm, what is that thing actually good for? ok well besides redirecting stuff. ;) Whats the impact if I'd turn it off? Is it just appending the conversationId to all kinds of URLs?
btw: can't tell you guys how much I appreciate your extremly fast responses all the time! Big big thanks for that! :) Without knowing that Gavin & Co. read and reply faster to posts then I can type I wouldn't have decided to use Seam in a production system with lots of customers on it.
