@darius, the idea is that based on set definition we identify the members, and based on the data type of each of its member, we would come up with a default UI representation (widget/control) for each of the member and present it in the UI. However we shall also provide an option to change the UI representation, say from Yes/No buttons for a boolean data type, it can be changed to say Radio Buttons.
Please expect an update on the Bahmni wiki which would explain the same in couple of days.
We shall discuss this idea internally and get back to you.
