Re: Form validation over multiple pages

[Paul Curren]

Hi there,
I've been doing this exact thing the last couple of days and I have it 
working.
My html:hidden tags looks like -

<html:hidden property="page" value="1"/>
i.e. only difference is I don't explicitly specify the form name.
My form is a DynaValidatorForm and a bug which i've seen from rc1 right 
up to the May 26 nightly so far means that I need to explicity define 
the page property on the form e.g.

<form-property name="page" type="java.lang.Integer" />

Hope this helps,

Paul C

With a little further investigation I see that the page value does not
get set in the validationForm using html:hidden approach as outlined
below. Ie, this doen't work:
   <html:hidden name="validateForm" property="page" value="1" />

When I print out the value of the page field in the action, it is still set
to zero.
How do you set the page property?

Also, this seems to imply the validator is VERY shaky over multiple
pages. For example, the properties on my second page are marked
as required, and they don't get validated in the first action (this seems
to show that the page based validation is working), yet on the second
page, the associated action tries to validate the page 1 properties!!!
Arrrg!! What's going on! Has anyone got this to work?

Subject: Form validation over multiple pages
Hi all,

I'm almost there with using the validator over several pages with a single
form.
However I'm getting a strange little error. The first page is validating
fine, and it
doesn't seem to try to validate the info required on the second page -
correct.
However once I try to validate the second page, the javascript validates
correctly,
but the server side validation returns an error saying the first page's
required field
needs validating.
I think it might be because I'm not sure how to pass the page parameter to
the action.
I've tried using a html:hidden tag. Anyway, snippets from the jsps, struts
config and
validation.xml file are included below.
If someone could help me out I'd be very grateful. Thanks very much,
Brian.


My first jsp named "validatestep1.jsp" looks like:

<html:javascript formName="validateForm" page="1"/>

<html:form action="/secure/validateStep1.jspa" onsubmit="return
validateValidateForm(this);" method="post">
   <html:hidden name="validateForm" property="page" value="1" />
<table>
<tr><td>username</td>
 <td><html:text name="validateForm" property="userName" /></td>
</tr>
<tr>
 <td colspan="2" align="center">
  <html:image border="0" page="/images/button_submit.gif"/>
 </td>
 </tr>
</table>
</html:form>
My second jsp named "validatestep2.jsp" looks like

<html:javascript formName="validateForm" page="2"/>
<html:form action="/secure/validateStep2.jspa" onsubmit="return
validateValidateForm(this);" method="post">
   <html:hidden name="validateForm" property="page" value="2" />
<table>
<tr>
 <td>credit card with no spaces or dashes</td>
 <td><html:text name="validateForm" property="creditCard" /></td>
</tr>
<tr>
 <td colspan="2" align="center">
  <html:image border="0" page="/images/button_submit.gif"/>
 </td>
 </tr>
</table>
</html:form>
in my struts config I have

   <action
     path="/secure/validateStep1"
     type="ValidateStep1Action"
     name="validateForm"
     scope="session"
     input="/validatestep1.jsp"
     unknown="false"
     validate="true"
   >
     <forward
       name="success"
       path="/validatestep2.jsp"
       redirect="false"
     />
and then

   <action
     path="/secure/validateStep2"
     type="ValidateStep2Action"
     name="validateForm"
     scope="session"
     input="/validatestep2.jsp"
     unknown="false"
     validate="true"
   >
     <forward
       name="success"
       path="/validated.jsp"
       redirect="false"
     />
In my validation.xml file I have

     <form name="validateForm">
             <field property="userName" depends="required,minlength"
page="1">
             <field property="creditCard" depends="required,creditCard"
page="2">
