I have developed a custom widget and the widget is working just fine. So I started writing the setting files for the configuration page. Unfortunately no matter how I try, when I add the widget to the app, it just show the loading screen for the configuration page, and I checked the network, it seems not loading Setting.js and Setting.html at all. However I can still click "OK" to skip the configuration and proceed to load my widget to the app.
How to debug the setting.js and setting.html?
Zhenyang,
What does your manifest.json look like? Have you checked your web browsers web console to see if there are any errors showing?
Looks like it is still the limitation of web appbuilder isn't able to clear the cache of the widget, I did some change to the WidgeManager.js and it works now. Thank you!
