I've created a simple Custom Python Class as described in the ZClass Tutorial, but I can't seem to call a python class method from a DHTML method in my derived ZClass. My Python module gets registered correctly. I went to Control Panel/ Products and saw my Package listed "Mercury". Under Mercury, I chose to create a new ZClass called Stats, which is subclassed from ModuleFactory, a class I registered in my Package's __init__.py Zope\Lib\Python\products\Mercury\__init__.py has import MercuryJobs import MercuryStats def initialize(context): """Called by Zope to initialize a product""" context.registerBaseClass(MercuryJobs.QueueManager) context.registerBaseClass(MercuryStats.ModuleFactory) ---- In the Zclass 'stat's, I added a new DTML method called getModules, and that method has: <dtml-var ModuleList> When I choose to view it, I get KeyError, ModuleList. Perhaps this can't be viewed until instantiated? Am I on the right track? MercuryStats.ModuleFactory returns a list of objects which I'll want to iterate over with #in. I'm expecting to add a "Mercury/Stats" object into a folder at some point, then #in on it to get the list of objects. Is this the correct way to call a method in a python base class from a DHTML method in Zclass?
