[Zope] Re: Methods in a Simple Class

[Alexandre Ratti]

Salut Olivier,


Did you solve your issue below? If not, please reexplain what you are 
trying to achieve.

If you want to render one of your ZClass with <dtml-var myClass> you may 
need to subclass "Renderable BaseClass" (available on the Zope site).

Or I am barking up the wrong tree?
