[Zope-dev] After migrate to 2.10.1 ManagableIndex throws TraversalErrors

[Ian McCracken]

I'm migrating the Zenoss code to Zope 2.10.1. I've moved to Five 1.5.1, 
CMFCore 1.6.2. Does anyone know if there's a quick fix for this problem?

Traceback (most recent call last):

I've been told it may involve a rewrite of ManagableIndex to use Zope 3 
adapters...any thoughts?
