[Zope-dev] Mixin required for Subobject in Z Class?

Tue, 27 Aug 2002 22:07:50 -0500

I have created a (so far very) simple Z Class that inherits from ZObject and 
ZObjectManager.  The Subobjects tab lets me select any kind of object *except* 
a ReStructuredText Document, which is provided by the ZReST 1.0 Product.  
Richard Jones, the ZReST author, suggested that perhaps a mixin class was 
needed in ZReST for this to work.  What is required here?

This is the response I get when attempting to add ReStructuredText Document to 
the Subobjects list of my Z Class:
