Ok, I am sure I follow the details here, but sounds like this does not work the way you would like it to work. And wrt generic container types (that is, `List<X>`), no type information is available thanks to type erasure, that is true. > I end up writing my own serializer / deserializer :) > https://gist.github.com/nithril/b55d6ab32db253dfe24995f87c899685 Ok, sometimes that's what you got to do.
