If in your model is enough to have Collections/Lists based on ArrayList you can easily convert from JsArrays to ArrayLists and vice-versa by using a bit of JSNI since the ArrayList implementation in GWT relies on a javascript array.
Take a look to this code used in the gwt-polymer-elements library (put attention to asList and asArrayList methods) https://github.com/manolo/gwt-api-generator/blob/master/lib/com/vaadin/polymer/Polymer.java#L522 - Manolo On Mon, May 8, 2017 at 10:27 PM, Marcin Okraszewski <okr...@gmail.com> wrote: > Basically what we need it for is REST.
