Correct--the ActionForm follows the standard JavaBeans approach--reduced learning curve for newcomers, and already generated by most IDE's. > What bothers me about the DynaBean approach is that > it's *yet another* > file, and *yet another* level of indirection that > obscure what's really > going on.

It's not "yet another" file, because DAF's were (I believe) originally designed to reduce the number of ActionForms you'd have to implement. I.e., if you don't have any special validation to do, don't bother subclassing an ActionForm--just put the variables in the struts-config and you're done. Very nice design. The problem was that the DAF class was not made final. Allowing it to be subclassed is creating the mess you describe--the variables in the XML file and actions on them in the DAF subclass. (Another was writing about putting member variable initializations in the validate() function--the DAF subclass may also start encouraging other messier programming habits.) As for those who don't like getter/setters and want to use the common-beanutils "get" functions described by Craig: Might it have been better, in addition to making the DAF class final, to just have ActionForms implement "get"'s interface?
