The "Default" record selection for Radio Button List does not work for manually triggered events.


1. Populated radio button list control on "When the view executed Initialize" rules  - The default value will be selected.

2. When Adding a new button, the populated radio button list control on “When Button is Clicked” rule - No any items are selected by default.

Both actions called to the same SmartObject and the rules are the same, but the result is different.


This has been logged as a bug to be addressed in a future version of the product.
