Hi Lars, I am not sure I understand totally about your problem, but this is what I think you want: When the user has an addForm for that ZClass - you want a default value for actual location? If this is the case - (AFAIK) you cannot access the property of the ZClass instance until you have created it. Thus you will have to hard code your default location into the addForm. <td><input type=text name=actualLocation size=60 value="your_default_location"></td> btw, I still haven't quite worked out how to use default properties yet i.e. the ones that are defined when you create a property sheet in a ZClass! hth Laurie -----Original Message----- From: zope-admin@zope.org [mailto:zope-admin@zope.org]On Behalf Of Lars Heber Sent: Tuesday, October 02, 2001 11:57 AM To: zope@zope.org Subject: [Zope] Use properties of a product? OK, I have a product, lets say AA. It has a property location. Within this product, I have a ZClass. In the addForm, I'd like to pass a standard value, which is the "location" property of AA, to the user within the form. He can change that value, and that value becomes a property of the ZClass, let's say "actualLocation". I could not find a possibility to access the location prop of AA. <td><input type=text name=actualLocation size=60 value="<dtml-var location>"></td> does not work. Any suggestions?
