The SpRadioButton bean appears as a radio button, and is used to provide one of a group of mutually exclusive setting choices.
This bean provides a set of default RadioButton types, each of which invokes a particular behavior when its state changes. Buttons of these types have the same functions as those of the SpButtons.
When a radio button is selected, a DSECoordinationEvent is fired, and the event gets its information from the "type" and "navigationParameters" properties of the radio button. The event name is the bean name (getName() method) with ".itemStateChanged" appended to it.
