Rails - Aug 2006 - Catching "keypress" event with observe_field

I''m desperately trying to update a div when a key is pressed in a text
field.

Eg. :

<input type="text" id="field">
<div id="area"></div>
<%= observe_field :field, :url => {:action => :myAction}, :update =>
:area, :with => "text_param", :on =>
''keypress'' %>

This does not seem to work, and I can''t understand why. Does someone
have any clue on what I am doing wrong ?

Thanks in advance

I don''t use AJAX, but I''ll see if I can help.

Just some thoughts:

1. Right click on the loaded page and view source to make sure 
javascript is in the headers. Maybe observe_field isn''t being loaded.
2. Instead of using keypress, does it work with frequency? I know that 
is not what you want, but it might give you some ideas.
3. Try text_field_tag as well for the input.

Yep, it''s loaded.

Already done that, and yes, it works very well.
