In case your RemoteForm misteriously behaves like a normal HTTP form, refreshing the page on submit, and the only hint that there's something wrong is this bit in the Iceweasel's error console:
the problem can just be a missing
action= attribute to the form.
I found out after:
reading the TurboGears remoteform wiki: "For some reason, the RemoteForm is acting like a regular html form, serving up a new page instead of performing the replacements we're looking for. I'll update this page as soon as I figure out why this is happening."
finding this page on Google and meditating for a while while staring at it. I don't speak German, but often enough I manage to solve problems after meditating over Google results in all sorts of languages unknown or unreadable to me. I will call this practice Webomancy.
