Quite contrary, this is exactly why collection of errors SHOULD be maintained in session-scoped action form: to survive redirects. This exactly what I do in my projects. Of course, now we face another issue: how and when to remove unneeded stuff from a form bean. But even if these messages would not be removed, the session size for each connection will not grow indefinetely, because there is only one message object per session. I think that usability is much more important than session size. > How would one be clear on the semantics of when a new ActionMessages should be > created vs. when the existing one should be augmented? Simple: Messages should be kept and shown once again, when page is requested by browser, until new input comes in, then messages should be cleaned and should get accumulated again according to new input data and model update. This approach requires cleaner development, with using POST for input only, and GET for obtaining output only. Works like a charm in my projects. > There has been plenty of talk about how to adjust ActionForm to remove the > direct dependency on the deprecated ActionErrors class; I believe the best > route > is to pass in an ActionContext object (new in Struts 1.3) and return void; Exactly! Returning void, that is what I do. I use session-scoped form bean and accumulate errors in the collection. Then I do redirect, and load a page with GET, restoring saved messages from form bean to request object.
