I'd need to know exact calls you are using (and probably `@JsonTypeInfo` definitions); class hierarchy itself is not sufficient. And perhaps specific failure you get. But one common problem is that users sometimes try to use a subtype as target type on deserialization (like `B` or `C`) -- but `defaultImpl` MUST be assignment compatible with given target type. So it could be that you were trying something like: B result = mapper.readValue(source, B.class); in which case you saying that base type of result value is `B`, and therefore `A` would not be assignment-compatible default type. -+ Tatu +- -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
