Exactly--that's the advantage of making the DAF final! If one wishes to have custom reset() or validate() methods, one needs to trot back to the ActionForm. The only programming/configuration of any type you should be able to do for a DAF is in the form beans section of the struts-config file. The DAF seems to me just a nice enhancement from 1.0.2 because you no longer need to create ActionForm subclasses for jsp's not needing validation. And AF is then for when you do have specific validation--and it would be good if we can give programmers the option in the future of using either the beanutils get()/set() functions or the JavaBeans getter/setter functions within the AF.
