I'm attempting to enhance the editing functionality found in the JavaScript Viewer produced by the Web App builder (Developer Edition). A simple version of what I am attempting would be creating a way to force the validation of an web address into a text box when editing a feature service.
From the research I've done so far it appears that I need to set the customField property within the layerinfo section config_edit.json for the appropriate field. When I do put something in there I'm unsure if it's correct because I'm not sure where it is ending up. It looks like it gets passed right through the editor widget.js code (it runs right throughh the getLayers function) and that the popup doesn't know what to do with it (other fields come in fine while my custom field has only a label and a blank spot where my custom dijit should be),
