This is more a question for DC than for the list: Will it be possible in the future to limit in what places users can add ZClass instances? I have one ZClass derived from ObjectManager, let's call it Container, and another called Element, a simple object, and I want to be able to add instances of Element to Container, but not to any other ObjectManager derived objects (including Folders). Right now, this means I have to provide an alternative to manage_main.. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-6254545 Fax: +31-35-6254555 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------
