[Zope] about the IMAPAdapter Product product

[Ibaņez Palomar Juan David]

The lines 106-108 of the file "IMAPAdapter.py" are:

def addIMAPAdapter(self, title='', default_domain='', 
               smtp_server='', smtp_port=25, imap_server='',  
               imap_port=143, roles, REQUEST=None):

the roles parameter has no default value while REQUEST has, this gives
me an error. Shouldn't it be roles=''?
 


And a question, the method validate begins:
    def validate(self, request, auth='', roles=None):
    """ """
    if 'NotMail' not in roles:         <---  Why these two lines?
        return None                    <---



Thanks for your time,
David
