Suppose, Joe, that we have first.jsp and second.jsp, FirstActionForm.java and SecondActionForm.java. We call MyAction.java as the action for <html:form> in first.jsp and want to setup the values in second.jsp via SecondActionForm.java. How would you configure the <action-mapping> for this use case, which I think is the most common use case there is?
<action path="/FirstAction" name="FirstActionForm" type="ProcessFirstActionFormAction">
<set-property key="view.formName" value="SecondActionForm" />
<forward name="success" path="/second.jsp" />
</action>
public class ProcessFirstActionFormAction extends Action { public ActionForward execute(mapping,form,request,response) {// perform business logic based on form, instance of FirstActionForm
String viewFormName = mapping.getProperty("view.formName");
ActionForm viewForm = methodWhichLooksUpForm(request, viewFormName);
// set up viewForm, which is expected to be an instance of SecondActionForm.java
}
}
Did I understand your question? This is assuming that you wanted to do everything in an Action, which isn't my preference -- but it's possible.
If I misunderstood, please clarify.

well, no, and I don't see why you can't using this arbitrary property map. I'm not sure what you think the best way for getting form objects from the properties (I think the framework could make it easier than it is now), but I think it should all be possible.
And the description I posted could have any number of FormPrepCommands -- something I have never needed myself but which was pointed out as a need on the list. I had originally envisioned just setting "name" and "scope" on the ForwardConfig itself, but one or more people brought up the use case you suggest, and my thought is that the per-forward chain supports that pretty readily. If you think I've missed something, please let me know.
