Multipage Validation - Show errors on page where first action occ urs

[Nicolas Pottrain <np...@reference.be>]

Hi everybody,
 
I will sketch my problem:
 
I have a multi page form, that consists of 3 pages.
There are next - previous buttons to navigate between the pages, no
validation occurrs when pressing next/previous.
The user can press submit on each of the 3 pages. 
When the user presses submit, then validation occurs.
I would like the error messages to show on the page where the first error
comes from.
 
If I use the page property in the field element, only the pages up to the
current page are validated,
so that's not an option, I want everyhting to be validated.
When I don't use the page property the errors show up on the page where I
pressed submit.
 
Is there a way to show the error messages on the first page where an error
occurrs?
For ex. I press submit on page3, I get a ValidationError : a required field
not filled in on page1
Redirect to page1 and show the error messages.
 
thx,
 
Nicolas Pottrain

Re: Multipage Validation - Show errors on page where first action occurs

use 3 actionMapping and 1 formBean with custom validate() :

submit -> /action1.do (validate form1 parameters) input="page1"
       -> forward to
          /action2.do (validate form2 parameters) input="page2"
       -> forward to
          /action3.do (validate form3 parameters) input="page3"

/action1 and /action2 are forward mappings

/action3 uses formBean for business.

validate() uses mapping to know what property to validate. You can
extend ActionMapping to add a property "validate" that you will set in
struts-config to the comma-separated list of form properties to
validate :

<action path="/action1"
        className="myActionMapping"
        input="/page1.jsp"
        forward="/action2.do">
<set-property property="validate" value="fistname, lastname,
birthdate"/>
</action>


Hope it will help you.

Nico.
