How to reference layers in map.reorderLayer

DanNorman — Sat, 11 Dec 2021 21:08:23 GMT

I have successfully added a feature collection of image services to my WAB developer edition application by using the following :Re: Editing LayerList widget to include multiple Groups/Divs of layers

now that I have added this group layer i would like to change the order in the layer list. I am attempting to use the this.map.reorderLayer() method in the startup function of Widget.js in server\apps\2\widgets\LayerList\Widget.js without any luck. I am guessing the problem is i do not know how to reference which layer i want to move! See line 28. What do i replace the first parameter with to reference my newly added layer?

Thanks!

        this.inherited(arguments);
