Just a clarification on my problem using Renderable. If I define a Zclass dtml method called index_html and have it call the render method, then non-folder objects render correctly. That is, if I have a zclass instance called X in folder Z, then Z/X renders. However if I have a zclass instance called index_html in folder Z, then Z/index_html does not render correctly, instead it just shows the DTML Method contents of Zclass Instance X Brad Clements, bkc@murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com AOL-IM: BKClements
