Unable to dynamically call an EOperation of a generated type [message #1859075]

So I have a bunch of generated classes each of which define several operations.

When I try to dynamically invoke an operation using its id

(List<EObject>) (eObject).eInvoke(operations.get(i), ECollections.emptyEList());

I get an exception thrown with the message

No InvocationDelegate registered to provide an eInvoke implementation for getDescribingFunctionalChains

From what I've seen it's because I have no InvocationDelegate or factory to pick it for my particular type, but how exactly do I generate that? Or is it a different problem?

Do you see a generated eInvoke method in your generated Impl classes? I.e., have you enabled the GenModel's Model -> Operation Reflection property for these models?
