[Zope] ZClasses, nesting, and properties

[Howard Shaw]

Note: My list subscription has fallen over and died, so please respond to me
as well as to the list. Thank you.

I have a ZClass with a property sheet called 'info'. On this sheet is a text
property 'contents'. The ZClass descends from Folder and Catalog Aware. When
I place an instance within an instance, and in a dtml document acquired from
above both instances call '<dtml-var contents>' I get the contents property
of the outermost instance.

Why is this happening, and how can I avoid it? Please help!
