One thing that is a pain about ZClasses is that when you want to call the method of a particular superclass, you have to do some really nasty digging with an external method to specify it, unlike in python products. This seems like it might be related to your problem. You would want to simply have your class call the manage_FTPget, manageFTP_list, manage_FTPstat, and PUT() of the PageTemplate class. In python, you would do this like: class A: def manage_FTPlist(self,REQUEST): #do something here class B(A): def manage_FTPlist(self,REQUEST): return A.manageFTPlist(self,REQUEST) But, alas, you need to get a reference to the class A, which is very hard in a ZClass. You could do likely this with some very deep digging in an external method (something resembling this): def getPageTemplateClass(self): clist = self.___class__.__bases__ #get tuple of all base classes for superc in clist: if superc.__name__ == 'ZopePageTemplate': return superc #return the ZPT class return self.__class__ #fallback/default: return our own class You would then need to create external methods for each of the 4 FTP methods named above and call the appropriate method of the ZopePageTemplate class returned by the above external method. The said methods would use the above method to get access to the superclass A lot of this might be easier in a Python product. The Zope Bible is a pretty good reference/tutorial for building products. My guess is that trying to do this as a ZClass would actually be harder than as a Python Product. Sean You wrote:

My ZClass is based off Page Template and CatalogAware (vis a vis a CatalogAware wrapper for Page Templates! Is there any reason the developers are not making older types CatalogAware to save us this trouble and make the ZCatalog that much more usefull? I digress.) I had hoped the inheritance from Page Templates would have handled the required functions, but it does not. I can see where I might begin to move towards a solution in a Python Product, but not at all with a ZClass. It's a pity, as I'm so very close to being where I want with this. If anyone has any further thoughts on manipularing the inner workings of a ZClass, I'd find that tremendously helpful. In lieu of that, a primer on how to make a Python Product would be nice as it looks like I'll be working overtime... But, for the time being, I'll work with the ancient patch mentioned previously to see if I can incorporate the features I desire into Zope 2.6 Ed
