[Zope] Mass update of a ZClass property?

wait, there's a small trick you can use
so that you don't need to write your own
method which recurses folders.

Just go to the "Find" tab of the folder where
the instances of your zclasses are and
go to advanced search.
Select your zclass type for search and put
manage_editProperties(Category=['Music','CD','Book'])
into "expr:".
Zope will find nothing, but the instances' properties
are updated after that.
