ParameterListActionDispatcher is a proposal for upcoming Struts release. The more people use it and find it useful, the more chances that it will be included. So, try it and vote for it if you like it: http://issues.apache.org/bugzilla/show_bug.cgi?id=38343 I hope you will like it, I think it is the best known solution for event dispatch in Struts. If you use Struts 1.2.7+, all you need is only ParameterListActionDispatcher class. Download it and compile it along with your project. If you use older Struts version than you will need base ActionDispatcher as well, but nothing more. > Regarding DataEntryForm - > * In sections 6 & 7 it describes a class > ParameterMappingDispatchAction that I also don't see in the > distribution (nor in the javadocs online).

Right, I have to fix that. ParameterMappingDispatchAction was an initial patch, then Paul went with ParameterListActionDispatcher which is better because you can use any Action class, you do not have to derive your Action from some other dispatch class anymore. So disregard ParameterMappingDispatchAction, I will fix the wiki page later. > All that aside, when I turn off automatic validation, can I still call > the validation manually in my action code? ie.

This is exactly how you do it, perfect. > Is there anything else I need to do to validate the form manually? No. You may want to check errors for null, but it depends on how you implemented validate() method.
