Rails - May 2006 - AJAX request not setting Accept header

I''m trying to stay DRY and use respond_to as I move to AJAX in my apps,
but
I''m getting some mysterious behavior. Here''s a simple form
I''m testing with:

<%= form_remote_tag :url => {:action => ''submit''}
%>
  <%= submit_tag ''Go'' %>
<%= end_form_tag %>

When I submit the following HTTP request is sent:

POST /test/submit HTTP/1.1
Host: localhost:3000
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.3)
Gecko/20060426 Firefox/1.5.0.3
Accept: text/xml,application/xml,application/xhtml+xml,text/html;q=0.9
,text/plain;q=0.8,image/png,*/*;q=0.5
<snip />

Notice that "text/javascript" appears nowhere in the Accept list!
Because of
this absence I would not expect respond_to to correctly catch the AJAX
submission, and it doesn''t. Instead HTML is triggered every time.

respond_to do |wants|
  wants.js { render } # Never triggered
  wants.html { redirect_to :action => ''WHY?'' } # Always
triggered
end

If I remove the "wants.html" line my RJS template performs the
expected
dynamic actions, so I know that Javascript is enabled, but I''m at a
complete
loss as to why the Accept headers are not being set... can anyone point out
what I am missing?

Hi Don (or anybody who can help! ;-) )

I''m having exactly the same problem.  Did you ever figure this out? 
Has anybody gotten respond_to to actually work?

Thanks,
Bill
