screenshots) in which I will be storing instances of a class I've built called
ScreenShot. The problem is that I can't figure out how to make the Folder
interface in the ZMI limit the instance types to ScreenShot. In the Site
class __init__ method, I have :</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV>
OFS.Folder.manage_addFolder(self, 'screenshots', 'Screen
Shots')<BR>
self.screenshots.meta_types=('ScreenShot')<BR></DIV>
<DIV>However, this isn't working. I looked into the Folder class, and
discovered that it's base class ObjectManager has a class property (not
instance) called meta-types that is a tuple. do I need to sub-class Folder
and set meta_types at the class level ? </DIV>
