Are you retrieving the same object that you saved again? Or are you creating another one?
Please add some screenshot of the page/radiobuttons and of the microflow that is providing the object for the dataview
When I press save I can see in the Entity model that data is saved from the radio button that I choose. But again when I load the page it don’t select the last stored radio button value.
Selected radio attributes are stored in DB. See screen dump. So it's very strange that they are not show up as selected when you enter the page
