Great! Any idea if Adobe will be releasing an official guide like above to showcase how to create Touch UI Multi Composite component (JSP / Slightly)?
I found this article, which I guess is not fully tested and not all the TouchUI dialogs will be supported. Rather primitive.
We use to have it in Classic UI (with this file /cq/ui/widgets/source/widgets/form/MultiCompositeField.js).
We will be working to put out a lot of these types of articles. One difference between helpx articles and other blogs is we fully test all of the helpx articles and have many community members involved too. So the content is based on real world community code created by AEM developers.
We also other community members test helpx articles.
I always list what articles are coming in my blog:
Notice that we have a real world Sightly Movie compoent that uses digital assets coming soon.
