Kevin Howe wrote a version of my ``Renderable base ZClass'' which plugs directly into the ZClass system. Background info: a Renderable ZClass is one with control of what happens when you <dtml-var some_object_of_this_class>. Kevin's version is really cool, but it patches stuff outside Products/Renderable, so I won't distribute it as the ``official'' Renderable Product. Still, I'd like to lobby for its inclusion in Zope itself. How it works: when you create your ZClass, you select ``Renderable'' as one of the base classes. Then (in Kevin's version) in the Basic tab you select some method to be executed when people <dtml-var some_object_of_this_class>. My BannerAd Product and Kevin's ActiveImage Product both use Renderable. AFAIK, both work with my version and Kevin's. []s, |alo +---- -- I am Lalo of deB-org. You will be freed.
