## Class ListUIBean

- java.lang.Object
- - org.apache.struts2.components.Component
  - - org.apache.struts2.components.UIBean
    - - org.apache.struts2.components.ListUIBean

- Direct Known Subclasses:
    CheckboxList, DoubleListUIBean, InputTransferSelect, Radio, Select

      public abstract class ListUIBean
      extends UIBean

  DoubleListUIBean is the standard superclass of all Struts list handling components.

  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.
