AbstractWizardFormController & Validation

[matthewramella]

Does anyone know of an easy way to disable validation in the event a user clicks the Back button while stepping through a form wizard?

I've come up with a potential solution, however, I don't think it's the most elegent of solutions. I was kind of hoping the Spring framework would automatically disable validation (or give you the option to automatically disable validation) in the event a user attempts to move backward in a wizard.

Anyhow, here's what I've come up with so far:

Override the suppressValidation method as follows:

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

Create the following isBackButton private method:

private boolean isBackButton(HttpServletRequest request){
try {
for (int i = 0; i < getPages().length; i++) {
String paramValue = RequestUtils.getStringParameter(request, "_target"+i);
if (paramValue != null && paramValue.trim().equalsIgnoreCase("back")){
System.out.println("Back button was pushed!!");
return true;
}
}

} catch (ServletRequestBindingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return false;
}

Thanks!

onBindAndValidate() {

if(page == 2 && WebUtils.hasSubmitParameter(request, "forward")) {
// some validate code
}

}
