I have no idea why it's not working, unless maybe it's a Mongrel-only thing (as opposed to using Mongrel and Lighty) -- but that's a shot in the dark. Or maybe it's related to using controller modules? If I add ":update=\>'test'" to the link tag, the div gets changed to "Element.update("test", "rails");" or "$('test').value='rails'" or whatever. I've restarted Mongrel many times, tried it in Safari, refreshed, checked my javascript settings (it does seem like the javascript isn't getting run for some reason), etc. -- all to no avail. Anybody have ANY idea what the problem might be? I'm getting cross-eyed...

Sounds like you forgot to put...

\<%= javascript\_include\_tag :defaults %\>

in the head of your layout file.

I'd get a copy of the firebug extension for firefox and see what the AJAX request/response looks like.
