We are trying to override the stock activity story widgets but they do not seem to be used in the rendering process
Firstly I tried to save a widget as a theme version and it all looked promising, the staged version appeared in widget studio but after saving it disappeared, I also tried this with other stock widgets and the same happened so not sure if this a bug
So I then created the files directly in the cfs adding the theme id to the xml file and it appeared in the widget studio as expected
But when viewing the activity feed in the IET theme it still shows the core widget ?
