Hi, sorry for digging up this old post. This seems like not such a rare
case. Is there a way to do it without any code (reusing existing standard
converters) today ?
I don't care if it's [ [ k, v], [ k, v] ...] or [ { key: k, value: v}, {
key: k, value: v},...], or even [{ myname: k, myothername: v}, { myname: k,
myothername: v}...]
On deserialization, I don't care about what happens if the input has
duplicates keys.
I think it's worth documenting in the main site (maybe it is and I missed
it ?). Actually I think that relying on toString() by default to serialize
maps<Complex,X> is surprising, and maybe it's worth adding a global option
to objectmapper to choose to convert all the maps<ComplexTypes, X> into
lists of key value pairs ?
Thanks in advance,
