Hopefully this is one of those dumb newbie questions that someone will be able to answer quite easily: I'm in Zope 2.3.0, and using a Python script to try to change a property of a DTML document, using a call like this: doc.manage_changeProperties({"foo":bar}) # doc, "foo" and bar are just examples I receive the following error: Error Type: KeyError Error Value: manage_page_header I get the same error trying to do a dtml-call to the method within the document. However, I'm able to execute manage_addProperty() successfully in both situations. Am I missing something? Big thanks to anyone who can point me in the right direction. I'm just starting up the learning curve here. :-) Gregg. -- Gregg Hartling hartling@earthlink.net
