[Zope-CMF] set the id of a new cmf object in the factory method

[Aaron Payne]

Hi all,

I'm trying to set the id of a new cmf object in the factory method and 
I'm hitting a wall.
I need to get an attribute of the cmf site and then increment it by 1.
In the factory method I have:

def addBibliography(self, id , title='', bibliography_reference_id='', 
volume='', search_words=''):
     """Create an empty bibliography."""

     portal_url = getToolByName(self, 'portal_url')
     currentN=portal_url.bibliography_reference_count
     newN=currentN+1
     id='BIB'+str(newN)
     bibliography_reference_id=id
     
portal_url.manage_changeProperties({'bibliography_reference_count':newN})

When I attempt to add an object to a folder I receive an AttributeError.

Traceback (innermost last):
   File /usr/local/zope/Zope2.5.1/lib/python/ZPublisher/Publish.py, line 
150, in publish_module

How does one get to the cmf site from the factory method?

thanks,
Aaron
