The BTTButtonGroup bean is used to provide a set of mutually exclusive
choices that appear as radio buttons.
Consistency between the bean and the context is maintained as follows:
- Every time a radio button in the group is selected, the data element associated
with the button group (and the alternative data element) takes as its value
the contents of the value property of the selected radio button.
- When the view is refreshed, the value property of the button selected
in a button group will contain the value of the data element associated with
that button group. If there is no radio button with this value, no radio button
is selected..
When nothing is selected, this bean will fire a DSECoordinationEvent,
and the event name will be "BTTButtonGroup.nothingSelected".
