Record duplication from a custom widget

[Emanuele_Gissi]

Just to clarify, this question is different from my previous one:

How to obtain the id of referenced records inside a custom widget?

I am developing a custom widget with a button that should duplicate a record. The record contains some reference fields and some reference list fields. The record returned by grist.onRecord(record) {} is something like: { "id": 14, "Name": "Andrea", "City": "Mi", "CalcId": 14, "Books": [ "Pride and prejudice", "Animal farm" ], "Books2": [ "La vita nuova" ], "Ref": "Convivio", "A": 14, "Addresses_City": [ "Milano", "Roma" ] } Note that Books, Books2,…

In that case I started using a formula column to obtain the ids of children records, and duplicate them.

This time I would like to code a generic record duplication function.
