I am in the process of creating container objects as a Python process. I want a result similar to the following structure. Resource Store - contains only Resource Folders Resource Folder - can contain multiple nestes Resource Folders and a Resource Source Resource Source - can contain only Resource Databases Resource Database - can contain only Record objects The Record objects have initially been developed as a stand alone product. My trouble begins in restricting the allowable meta_types to only one meta_type. From within my Resource Database, the factory method is not found. If I allow another metatype to be added, everything works fine. My Record objects can also be added to any other standard Zope object. I have even went as far as to place my Record product inside the Resources product. In doing so, I included a factory method for the top level of the Record inside my Resource Database class. The record is then added, but top level icons are lost. The way things are behaving for me have totally defied my understanding of how products operate inside Zope. Can someone help me understand what is going on? Why is the behavior different simply because I allow one vs. more than one metatype to be added?
