I haven't gotten to that point in the book, but just now, I installed
chapter 7 as worldcookery, got the error, then went to
browser/configure.zcml, commented out the widget elements in addForm
and editForm, and now I can add a recipe, edit its attributes, and
preview it. I suggest investigating what's changed with widgets in
Zope 3 since the book was published.
