Rails - Apr 2006 - piggybacking an action on an autocompleted field

Hi everybody,


I''d like to add a custom action to be triggered after/when an 
autocompleted  field has been/is beeing updated by the autocompletion 
process.
I tried the obvious - a field observer -, but it doesn''t work (see code
below). I know I could write the autocompletion code myself, but I 
wonder if there is a simpler/more elegant way?

Any idea?
TIA

Alain


The observer solution (that doesn''t work):

    <%= text_field_with_auto_complete :city, :zip    %>
    <%= observe_field("city_zip",
       :frequency => 0,
       :url => { :action => :get_names_for_zip },  <<<---- IS
NEVER
CALLED
       :with => "''zip=''+value") %>

There''s already a tiny patch - 3691 - in the waiting list that solves 
that very problem, and lets you write
      <%= text_field_with_auto_complete :city, :zip ,{},
	        :after_update_element=>
"alert(''after_update_element...'')"
       %>

    [PATCH] Add frequency and afterupdateelement option to 
text_field_with_auto_complete

It justs adds 2 lines in the _auto_complete_field_ method 
(java_script_macros_helper.rb)
         js_options[:frequency]  = "#{options[:frequency]}" if 
options[:frequency]
         js_options[:afterUpdateElement] = "function(element,value) { 
return #{options[:after_update_element]}(element,value); }"  if 
options[:after_update_element]
