This behavior has been bothering me as well - as Ed points out, the
possible solutions are more fraught than you might expect - but your
email (and embarrassing example) gave me the impetus to look at it
again, and I have an idea to try out, though it's one of those "so
simple I can't possibly be the first to think of it" sort of ideas, so
we'll have to see if it actually works.
I've opened up bug # 1208 to track the issue in Mojarra - I'd encourage
you to post any other implementation bugs you find to our bug database.
