[Zope-dev] Calling Python method from subclassed ZClass DTML method ?

[Brad Clements]

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?
