I just ran into this very problem myself. Yes, this is a bug in prototype.
If you look in the code you will see that the relevent handlers and
callbacks simply aren''t called with a synchronous request (onComplete
is
similarly not called).
I submitted a patch <http://dev.rubyonrails.org/ticket/4657> over at
dev.rubyonrails.org which fixes this behavior. If you decide to check it
out drop a comment on the patch as to whether it works for you.

Three passions, simple but overwhelmingly strong, have governed my life: the
longing for love, the search for knowledge, and unbearable pity for the
suffering of mankind.
