Text_field_with_auto_complete nonsense (newbie question)

Hi everyone,
I have been introduced to ruby on rails a couple of days ago and it
really brings out the fun in programming for the Web. I’m trying to
implement a text_field_with_auto_complete as described in
script.aculo.us , as follows:

controller:
class SearchController < ApplicationController
auto_complete_for :recipe, :name
end

search.rhtml:

<%= javascript_include_tag :defaults %> <%= text_field_with_auto_complete :recipe, :name %>

The result, however, is an unresponsive site, with the following output
from LightHTTPd:

Processing SearchController#auto_complete_for_recipe_recipe_name (for
127.0.0.1 at 2006-06-25 18:56:27) [POST]

Any ideas on what could be wrong? I tried a Recipe.search on the console
but it gives me the same error.
My database has a ‘recipes’ table with an id and a name string.

Thanks in advance,
Ricardo
