RE: Programmatic Validation in Action
Sure, it's really simple: action name=save class=exampleAction // this is action is configured in spring result name=input/update.jsp/result result/update.jsp/result result name=error/update.jsp/result /action When it goes to the input result, the values I typed in are no longer present. -Original Message- From: Dave Newton [mailto:[EMAIL PROTECTED] Sent: Saturday, June 09, 2007 2:49 PM To: Struts Users Mailing List Subject: Re: Programmatic Validation in Action --- Matt Luce [EMAIL PROTECTED] wrote: Has anyone attempted to use programmatic validation in Struts 2?

ModelDriven interface
I'm working with Struts 2.0.6 and I'm trying to use the ModelDriven Interface. However, I seem to be having some troubles. My actionClass implements ModelDriven, but the values on the page don't fill with the values of the object returned by getModel(). If I explicitly declare the getXxx() methods for each attribute of the model within the Action, the values are populated in the .jsp form.

Re: ModelDriven interface
Then why have the modelDriven interface at all? What use is it? Matt Luce Wells Fargo Funds Management, LLC 414.577.7927 414.359.3537 Fax
Re: ModelDriven interface
I agree, it should be on the stack, but the values don't show up. Does anyone have an example of this that works?
Re: ModelDriven interface
I'm using the default stack. What I'm trying to do is something very simple, that was incredibly straightforward in Struts 1. What I'm finding is the getModel() method is not getting called when I expect it to. It doesn't get called until after the action has been hit once. But that doesn't help, because the input page doesn't hit the action until the form is submitted. So somehow, I need to get my bean (the object returned by getModel()) on the ValueStack before the input page is rendered. I have no idea how to do that. In Struts 1, all I had to do was create the form bean in a pre-action, throw it in session, then forward to the input page. I don't know why Struts 2 doesn't allow for something that simple.
RE: ModelDriven interface
Here is the flow of my tiny app:
listAction - list.jsp - selectAction - update.jsp - updateAction
(implements ModelDriven - getModel() returns the object selected in
list.jsp stored in session )
Once it gets to update.jsp, the form should show the values of the bean
selected on list.jsp. But, since getModel() is not called until the
update.jsp is posts to updateAction, the model is not on the value
stack.
