Close, but it still doesn't work.
The widget is displayed and works on the client, but I am unable to 
insert ingredients.
Every time I click 'add' on the form, the ingredients list comes back 
empty and the recipe is refused (an error occured; there are 1 input 
errors).

I'm using Firefox 1.5



I'm attaching the list of changes I've applied to the book example 
(chapter 17). Basically, the one above + the alternateViews and pdf ones.
