AbstractWizardController Validation Back Button

[thus]

I have implemented a 4 page account creation wizard using the AbstractWizardFormController.

Form submission and validation appears to work as intended going forward through the wizard.

I run into problems when I traverse back from say Page 2 to the previous page in this case Page 1 resulting in validation errors from page 2 displayed on Page 1.

Works as intended:
Page0 ->(Validate)-> Page1->(Validate)->Page2->(Validate)Finish

Does not work as intended:
Page0->Page1->Page2(Leave required fields empty)->Page1 results in Page 2 validation errors being displayed on Page1.

Is there a parameter or method I need to set/call to clear all validation errors when navigating backwards through AbstractWizardFormController pages?

My validate() method in the controller uses a case statement to validate each page as the wizard is traversed like so:

validate(command,errors,page,finish){
    AccountValidator accountValidator = (AccountValidator).getValidator();
switch(page){

case 0:
   accountValidator.validateUserDetails();
break;

case 1:
   accountValidator.validateAccountDetails();
break;

case 2:
   accountValidator.validateDepositDetails();
break;
}
}

thanks in advance.

thus,

Did you ever find a solution to this problem? I too have run into this problem and wrote the following code to resolve the issue, however, I do not think it's a very elegent solution... At any rate, here's the code:

Private method in my Wizard controller:

private boolean isBackButton(HttpServletRequest request){
for (int i = 0; i < getPages().length; i++) {
String paramValue = (String)request.getParameter("_target"+i);
if (paramValue != null && paramValue.trim().equalsIgnoreCase("back")){
return true;
}
}
return false;
}

Override the surpressValidation method as follows:

protected boolean suppressValidation(HttpServletRequest request) {
return isBackButton(request);
}

This assumes that you've used the word 'Back' for the value of your HTML button, for instance:

<input type="submit" name="_target0" value="Back">

If anyone has a more elegent solution, please let us know...

Thanks!
