This is the strangest thing, within Web app builder developer edition; I am not able to add widgets into header controller for my web app. When I try to add a widget, the widget’s code does show within the Config.JSON file, but the widget does not show in the app. I have no idea what is going on. I’ve looked into the widgets Manifest.JSON file to be sure the widget’s “in panel” property is set to true. What else can I look at to resolve this issue?
