/**
* All actions mapped through the BeanAction class should be mapped
* to a subclass of BaseBean (or have no form bean mapping at all).
*
* The BaseBean class simplifies the validate() and reset() methods
* by allowing them to be managed without Struts dependencies. Quite
* simply, subclasses can override the parameterless validate()
* and reset() methods and set errors and messages using the ActionContext
* class.
*
* Note:  Full error, message and internationalization support is not complete.
