Unfortunately I think this is not supported. It gets quite difficult to support multiple levels of resolution when Annotations only allow reference to type-erased classes as values. You may be able to override `refineDeserializationType()` to do what you want, as you can control the logic using additional information (as you know bit more about type structure), and doing that would make sense to me and be supported to the degree that more advanced type resolution is legit use case. -+ Tatu +- -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
