I don’t know what json or obj are here, so it’s hard ot say what’s possible. But you may be able to do something like:

val msg = json { obj( "a" to "b", "notes" to mutableListOf() ) }

(msg.array("notes") as MutableList).add(element)

yeah that’s Klaxon’s dsl hehe

But presumably, json {} converts obj to json, so your array has already been serialised.

[viralshah]

I see good point

[Tim Malseed]

So as Jonathan says, you would need to populate the array before serialisation, and once serialised, you can’t change it.

[Tim Malseed]

If you need to modify the contents, you’re better off either doing so before passing obj to the json {} function, or deserialising, making your changes, and then serialising again
