Related Table Charts - "select search fields" not working
I'd like to use the out-of-the-box Related Table Charts widget in an app, but there seems to be a bug. There is no field-selector button present next to "Search Fields" when configuring a layer as a search source (screenshot 1). This functionality is present in the default Search widget, however (screenshot 2). There doesn't appear to be any way of setting the search field without this button (ie: simply typing the desired search field does nothing).
This bug is present in both Web AppBuilder Developer 2.10 and ArcGIS Online Web AppBuilder (non-developer). I'd like to find a workaround for this - perhaps by editing the .js in Related Table Charts, and re-deploying it as a custom widget in developer. Unfortunately, I'm not too familiar with JavaScript. Can anyone point me in the right direction?
Thanks!
