Evan, that document told me everything I needed to know. Thank you for pointing it out. My problem was that my Property class did not inherit from Acquisition.Implicit, thus rendering the security infrastructure unusable. Thanks again!

If you haven't already, read http://dev.zope.org/Wikis/DevSite/Projects/DeclarativeSecurity/ZopeSecur ityForDevelopers, in particular the example right before the paragraph that starts with: "Note the last line in the example. In order for security assertions to be correctly applied to your class, you must call the global class initializer for all classes that have security information." Hopefully this will solve your problem. Cheers, Evan @ Zope
