There is an interesting article talking about validation in DispatchAction. That may not be what you are looking for but I would like to know if the method suggestted by the author is a good choice or not: http://www.reumann.net/struts/articles/request_lists.jsp
Another common practice is to have a isMutable() method in ActionForm. However, it relies on the Actions to play around the 'mutable' property carefully. And is something goes wrong and the property is set/reset properly, then things may go wild.
