You're sure you need both indexes and metadata columns?

This is what pdb is for. ;-)
Put one in __init__ and one in __call__ and see if they're called at
all, and what happens.
One thought is that if the self.data = IMyBehaviorInterface(context)
fails, it'll raise a TypeError, which will become a "could not adapt"
in plone.indexer, which will then ignore that indexer.
