[Zope] Re: Some questions about ZCatalog

[Itai Tavor]

Just thought of a possible solution to the last problem... add a 
method to the object, named title_of_parent, which returns the 
parent's title. Tell the catalog to index title_of_parent. Take a 
vacation.

Makes sense? Good solution? Comments?
