[Zope] creating an instance of your own product within Python Scripts

[Tom Deprez]

Hi,

What do I've to accomplish to call

context.documents.manage_addProduct['OFSP'].manage_addFolder(id='new_id2')

with my own product? eg:

context.documents.manage_addProduct['OFSP'].manage_addCasusDocument(id='new_
id2')

I've already made it possible to import manage_addCasusDocument through
python scripts.
However now I'm stuck and don't know how I can create an instance of my
product inside a BTree folder

Thanks in advance,
Tom.
