Please make sure you have read the Tag Syntax document and understand how tag attribute syntax works.

Important

Note that the listkey and listvalue attribute will default to "key" and "value" respectively only when the list attribute is evaluated to a Map or its descendant. Everything else will result in listkey and listvalue to be null and not used.

Examples

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.
