CatalogAware ensures that objects are added to the catalog *when they >are created*. The easiest thing to do would be to use the Find >command in the Catalog to add the objects.

Ok, I know that... But in my case the best way is to have my objects indexed in the catalog automatically *when created* adding this base class. My problem remains with my older instances before the adition of the CatalogAware base class. They are somehow broken but I cant debug that.

BTW, those objects are aware that they have CatalogAware as a base

No :( thats not the case. I can delete with no prob. I've made restarts and still the older instances arent aware that they have CatalogAware as base class. Something is wrong, but I dont no what because everything looks ok, no broken products, etc. The new instances I create are aware of the new base class, but the older ones are just something apart from my and zope's logic. Anyway, thanks Kevin. ps. I love kmnetnews ;-) ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
