Do you have any progress on it ? I also have the same issue .
its a disgrace how not even at one place it is mentioned how to fill that stupid data provider selection box. I have searched through various documentations, and also searched on internet, and also tried going to dashboards> business dashboards> administration>data providers... but that shit didnt work. And frankly im getting a bit pissed of as you can see. Im writing my thesis, and cant continue because i cant populate one simple boolean/radio group? got to be kidding me.
