hi. i can't get _q_access to work. when i understand this right, all i have to do is derive my root-directory from Directory and AccessControlled and then define _q_access in my root-directory. i did this, but _q_access isn't called. the root directory has Directory's instances as attributes and publishes them. i'm using simple_server and took the http-auth example from wiki to implement _q_access any hints? regards, alexander
