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