Huh? Usually you have no chance to create a Zope object with such an id. So there is no need to rename something that can't exist be definition :-)

Exactly. The said object, "s5/Begin", is the "Begin" activity of the "s5" process found in the "GeneralWorkflow" workflow - which is an OpenFlow ( www.openflow.it ) object. I was able to rename my processes (S5, S100, S200) to their lowercase counterparts since all I had to do was do : /////////////////////////////////////////////////////// wf = container.GeneralWorkflow catalog = wf.Catalog processes = catalog.ZopeFind(wf, obj_metatypes=['Process'], search_sub=1) for p in processes: wf.manage_renameObject(p[0], p[0].lower()) /////////////////////////////////////////////////////// When I try to rename the activities found in those processes, I try to do likewise, but the ZopeFind results come out like this : ('S100/Begin', <activity at /dev/danny/wms/GeneralWorkflow/S100/Begin>) ('S100/RECEIPT_OF_SOURCE_DOCUMENTS', <activity at /dev/danny/wms/GeneralWorkflow/S100/RECEIPT_OF_SOURCE_DOCUMENTS>) ('S100/CHECK_MS_BATCHING', <activity at /dev/danny/wms/GeneralWorkflow/S100/CHECK_MS_BATCHING>) To call manage_renameObject (), I have to supply it with the object name. If I use result[0], I get the illegal characters in URL error. And if I use result[1].id, I get : Error Type: AttributeError Error Value: Begin This is probably because there is no "Begin" object under the "wf" container from which I'm calling manage_renameObject(). So my question is, how do I refer to the "Begin" object found in the S100 workflow ? Regards, Danny
