Hi Alexander, There was a hack some time ago that allowed to change the base classes for a ZClass. I used it once or twice in 2.0.1. I've never used it in 2.1b. Take a look at this email: <http://lists.zope.org/pipermail/zope-dev/1999-August/001288.html>. It contains explanations and an external method developped by Andreas Kostyrka. Be careful with it: better back up your database before trying it! Cheers. Alexandre At 20:40 16/11/1999 -0800, you wrote:

I have a bunch of ZClasses that aren't descended from the catalog-aware class-wossname. I need to make them catalog-aware. How do I easily do this? Can I export to XML and somehow import them in again?
