[Zope-CMF] DiscussionItem replacement

[Pierre-Yves Landuré]

Hi,

i'm willing to make comments by default 'pending'. But the 
DiscussionItem type defined by CMFDefault set the default state to 
'published'.

So i've made a modification of DiscussionItem.py, and tryed to register 
it to zope using a product named "DiscussionItem".

The product seems to work well, but the DiscussionItem type used by zope 
is the one defined by CMFDefault.

How can i force Zope to use my redefining of DiscussionItem ?

Thanx for help
