I am developing a custom user folder (based off of AccessControl.UserFolder code, and SimpleUserFolder), which inherits from BasicUser.
There are two types of users in this folder, one is the AccessControl.User, and the other is a subclass of it.
Inside getUserNames, I am trying to use isinstance, but it isn't working. It returns:
TypeError: isinstance() arg 2 must be a class or type The idiom for using "isinstance" for an "ExtensionClass" looks like:
try: isAnInstance= isinstance(object,ExtClass) except TypeError: isAnInstance= 0 # now "isAnInstance" is true when "object" is an instance of "ExtClass" Dieter
