> In our current application, we have about 60 jsps.  The pages are set up in a 
> wizard-like interface.  Depending on the data entered, a different path through 
> the pages will be taken.  All data is captured in a single ActionForm, so we 
> are using multipage validation.
> Each page is numbered, but the pages are not numbered sequentially.  Depending 
> on the data entered, a user on page 10 may be taken to page 8 or page 12.  In 
> the current way that the multipage validation works, if there is a required 
> field on page 8, but the user has been taken to page 12, it will generate an 
> error requiring the field on page 8.
> It would be nice if there were a flag that could be set that would allow the 
> validate method to only validate the current page, rather than all pages less 
> than or equal to the current page.  This would then need to be integrated into 
> struts to set the flag.
> Here is an example of how it could be done:
>     public ValidatorResults validate() throws ValidatorException {
>         ValidatorResults results = new ValidatorResults();
>         Locale locale = null;
>         if (hResources.containsKey(LOCALE_KEY)) {
>             locale = (Locale) hResources.get(LOCALE_KEY);
>         }
>         hResources.put(VALIDATOR_KEY, this);
>         if (locale == null) {
>             locale = Locale.getDefault();
>         }
>         if (resources == null) {
>             throw new ValidatorException("Resources not defined for Validator");
>         }
>         Form form = resources.get(locale, formName);
>         if (form != null) {
>             for (Iterator i = form.getFields().iterator(); i.hasNext();) {
>                 Field field = (Field) i.next();
> /***********************************
>  Check for the flag here 
> ************************************/
>                 if (validateCurrentPageOnly) {
>                     if ((field.getPage() == page) && 
>                         (field.getDepends() != null)) {
>                         validateField(field, results);
>                     }
>                 } else {
>                     if ((field.getPage() <= page) && 
>                         (field.getDepends() != null)) {
>                         validateField(field, results);
>                     }
>                 }
