[Zope] Creating an object from within another

[Chris McDonough]

I haven't gone back to look at the history of this thread, but it seems
you want to call something like;

self.manage_addProduct['SimpleSite'].manage_addBasicDocument(id='index_h
tml', title='')

(manage_addProduct is a mapping of Product name to Product object.  as
long as you've registered the constructors for SimpleSite in the
__init__ of the Product, you should be able to get to them like this).
