Rails - Jun 2006 - observe_field and radio button... does not work?

I try to catch click event on radio button, but nothing is executed....
Tested with RoR 1.1.2 and 1.1.3. What am I doing wrong?

<%= radio_button_tag(:city, ''Dublin'') %>

<%= observe_field(:citi, :frequency => 0.5,
                         :on => ''click'',
                         :with => "''city='' +
$F(''citi'')",
                         :url => { :action =>
''remote_city_choosen'' })
%>
...
def remote_city_choosen
  puts ''#'' * 60   # nothing is displayed
  p params[:citi] #  on the console :(
end

I think this is a simple typo issue, your field is named city, whereas
you are observing citi :)

Two things here:

The first parameter to observe_field is the id of the field you''re 
observing.  In your case the line should start
<%= observe_field(''city'' ...
I''m not sure if a symbol will work.  If it does, great.  If not, go to
a
quoted string in both the radio_button_tag and observe_field statements.

The default for radio_button is onchange so, unless you''ve some other
reason
for wanting to monitor it, you don''t need the :frequency setting.

Again, the default is for a radio_button is ''onchange''.  You
don''t need the
:on.

The explanation in the documentation for the :with option is, IMHO, entirely 
incomprehensible.  That''s probably because you can do more complicated
stuff
with it than most folks want/need to do.  What :with does, in cases like 
yours, is allow you to name the param in which the value in the field
you''re
observing will come back. So to get the value in the controller with 
params[:city], all you need is :with => ''city''.

hth,
