Hi, I've got a set up where I'd like to have Zope call an object method when someone tries to access the object to determine if they're allowed to do whatever it is they're trying to do. Is this possible? Or do I need to stick with __ac_permissions__ and friends? If so, what's the way of specifying which permissions a role has within the class definition? Thanks. -- Benno Rice "No, no. We're *sweet* and XNFP Aries Dark Subculture- *innocent* evil bastards." friendly Internet Geek benno@netizen.com.au "Defend your joy"
