after a couple days of posting...finally SOLVED with lots of different input from others.!!! Thank you to the community. I still cant get it to work in DTML (any guidance on this?), but have successfully created my first Python script. very cool. Python script 'the_list' # create a multiple selection list for a zClass Property, by calling the ID's of a different zClass('anotherZclass') in a folder(folder_of_anotherZclass) within the site. myList=[] for id in context.REQUEST['PARENTS'][1].folder_of_anotherZclass.objectIds('anotherZcla ss_meta_type'): myList.append(id) return myList PARENTS controls where the target folder is in the site. (alter as necessary)

From within zClasses, it has to be hard-coded from what I have been told. There is no way to do sloppy acquisition, dtml-zope-like. Enter 'the_list' as your Value in the Property Sheet, and it should work.

Use caselet: From "edit" in a zClass, dynamically render a selection list of related content(other zClasses) from a folder. The other zClasses can now be linked to this zClass using the 'ID' in a list of related links. one more step ahead, -Trevor
