37: * <!-- START SNIPPET: exdescription -->
38: * In this example, a radio control is displayed with a list of genders. The gender list is built from attribute
39: * id=genders. The framework calls getGenders() which will return a Map. For examples using listKey and listValue attributes,
40: * see the section select tag. The default selected one will be determined (in this case) by the getMale() method
41: * in the action class which should retun a value similar to the key of the getGenters() map if that particular
42: * gender is to be selected.<p/>
