Yes, page parameters don't seem to keep it. My use case is more common than a theme change. The user is browsing some bookmarkable articles, and if he wants to add a comment he has to log in and stay on the same page. After the log-in the GET params disappear. One workaround is to use a4j login action and rerender the the needed parts, which is a bit more complicated (and bugged with richfaces right now).
