I have a DateRanges object that, while having a "start" and "end" member, is deserialized as a primitive array, e.g. ['20130210-20130315','20130520-20130524'] rather than

[
  {
    "start":"2013-02-10",
    "end":"2013-03-15"
   },
  {
    "start":"2013-05-20",
    "end":"2013-05-24"
  }
]

since I use @JsonValue in the Set<DateRange> getter. (And DateRange has it's start and end elements ignored with @JsonIgnore.)

That said, my Json object already does this properly (and I have custom deserializer for each in the ObjectMapper), but I don't believe I have a way of telling Swagger to use my parser. The model it shows in the UI is totally off.
