Hello society !:-) Lots of thanx for all previous advices. Another question: My DTML document, containing <dtml-tree> tag persists in ZClass. I create an instance of the class in some folder. Now if I call that document, I don't see any tree at all, but I'd love to see the tree based on the folder, instance of ZClass is created in. Does anybody have an idea related to this ? I'd appreciate a couple. Thanx in advance, Anton.
