I'm trying to use dtml-tree to create a selective menu of objects based on whether or not the object has an "add_to_menu" property.

The bigger problem seems to be the namespace issue that Dieter was speaking of.
I found a solution that is much easier than hacking the TreeDisplay code: You do not plan to use REQUEST for information about the request but only as a container for a temporary list. This can be achieved without REQUEST <dtml-with "_.namespace(r=[])"> <dtml-in "objectValues()" sort=id> <dtml-if "_.has_key('add_to_menu')"> <dtml-call "r.append(_.getitem('sequence-item'))"> </dtml-if> </dtml-in> <dtml-return r> </dtml-with> Dieter
