Hi, I have a need to modify a Zope product so that at least one of it's classes becomes catalog aware. All the documentation I can find on catalog awareness refers to building ZClasses and giving them this feature; but the product I need to modify is built with external python code that resides in the "Products" directory. I understand though that it is possible for a product to be built which is a hybrid of Python code and ZClasses. So perhaps it is possible? Right now I'm having to use a workaround that changes the properties of a dtml document each time I need to catalog a new item of the product class concerned. I then re-catalog the same dtml document with the new properties; but this is taking to much of a toll on performance. Can anyone advise me on this? Thanks geoff
