RE: Multiple "input" within one Action?

[Zheng, Gang]

Thanks for the help. I think I will call the validate() from within the
action.

I can pass on some help recently provided by others, plus what I did. You
can either have a separate action mapping for each, if you want to have the
validation framework do all the work, or, you can do what I finally ended up
with:

        use all the validation rules, etc.

        but call validate() from your Action

        then, based on your current page and the button you
        pushed (back, next, done), send them to the correct page.

        actually, if they hit a 'back' button (not the browser's back
button)
        you don't want to validate anyway.

Here's a snippet from my config file - /go2wizard has the input= to get the
initial tile loaded, and then everything else is handled by the /wizard
action.
        
         <action path="/go2wizard"
                 parameter="sandbox.wizard.page1"
                 validate="false"
                 name="wizardForm"
                 type="org.apache.struts.actions.ForwardAction">
         </action>

         <action path="/wizard"
                 type="torch.webapp.sandbox.action.WizardAction"
                 name="wizardForm"
                 scope="session"
                 validate="false">
             <forward name="failure"
                      path="/do/go2wizard">
             </forward>
             <forward name="page1"
                      path="sandbox.wizard.page1">
             </forward>
             <forward name="page2"
                      path="sandbox.wizard.page2">
             </forward>
             <forward name="done"
                      path="/do/wizard/success">
             </forward>
         </action>

HTH,
