How should I modify the custom widget in the recipe examples to make it
work with 3.2.0 ?
As it is, the program does not work from chapter 7 onward
I get this on zope.app.form.browser.SimpleInputWidget at every attempt to
display the widget:
instance = self._widget_factory(*args)
TypeError: __init__() takes exactly 4 arguments (3 given)

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.
