You need to define an adapter from ExtensionClass.ExtensionClass (I think 
that's the right type) to dispatch.interfaces.ICriterion.  The adapter you 
should use is dispatch.strategy.ClassCriterion.  Something like:

     protocols.declareAdapter(ClassCriterion, [ICriterion], [ExtensionClass])

Let me know if that doesn't fix it for you.
