I am trying to access the Class Attribute values (meta_type, class_icon, class_id, etc.) from a simple base class by doing the following: import Aquisition class myClass: def __str__(self): meta = self.classMetaType() return meta I've also tried: meta = classMetaType() return meta and : return self.getClassAttr('meta_type','') but none of these seem to work. How do you retreive these values? KH
