Advantage of DyaActionForm over ActionForm?

with the use DyaActionForm , we can define the form properties in strus-config.xml instead of creating new form bean class.The only a开发者_JAVA技巧dvantage i can think is it will provide is the properties defined in xml file there will be no need of compilation and reduce the development time. Is it the only main pupose of dynaAction Form?

It helps keep your code base slim. Less to test, less to break, etc.
