[Zope-dev] method attribute __roles__ in Zope 2.8

[Andreas Jung]

I can across the following problem while trying to fix the broken FTP 
service for Zope 2.8:

ObjectManager.manage_FTPstat() tries to access 
self.manage_FTPlist.__roles__ whose
value is ('Manager',') in Zope 2.7. In 2.8 this attribute is not available. 
Can someone  explain
how and where is attribute in set Zope 2.7 and why it is no longer 
available in Zope 2.8 (has
it anything to do with new-style classes in 2.8).

Being-completely-clueless,
Andreas
