Unfortunately, this is as good as it gets. Take a look at this thread
for more information.

Thanks Ben for your help, but unfortunately it doesn't work as expected.
It redirects correctly to the form page but loses all the form values
and error messages.
My handle code:
public Resolution handle(FileUploadLimitExceededException
exception, HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
LOGGER.warn(exception.getMessage());
/*
* This is a hack from Ben Gunter received in the Stripes
forum. It is related to Jira issue:
* http://stripes.mc4j.org/jira/browse/STS-402. The problem is
that when the exception handler is called, it
* always receives the original request passed to the
StripesFilter and not the wrapped request. That prevents
* construction of the FlashScope in which we need to store
the error message.
*/
final StripesRequestWrapper wrapper = new
StripesRequestWrapper(request) {
/**
* Ignore multipart content and set the locale at the same
time.
*
* @param request the HTTP request to wrap.
*/
@Override
protected void
constructMultipartWrapper(HttpServletRequest request) throws
StripesServletException {
Locale locale =
StripesFilter.getConfiguration().getLocalePicker().pickLocale(request);
setLocale(locale);
}
};
// get referer URL
URL referer = null;
try {
referer = new URL(request.getHeader("referer"));
} catch (Exception e) {
throw exception;
}
// convert referer path to context-relative path
String path = referer.getFile();
String contextPath = request.getContextPath();
if (contextPath.length() > 0) {
if (!path.startsWith(contextPath + "/"))
throw exception;
path = path.replace(contextPath, "");
}
// create action bean and context
Configuration config = StripesFilter.getConfiguration();
final PVoucherActionBeanContext context =
(PVoucherActionBeanContext) config.getActionBeanContextFactory()
.getContextInstance(request, response);
final ActionBean actionBean =
config.getActionResolver().getActionBean(context);
// try to guess the field name
String fieldName = ValidationErrors.GLOBAL_ERROR;
try {
BeanInfo beanInfo =
Introspector.getBeanInfo(actionBean.getClass());
for (PropertyDescriptor pd :
beanInfo.getPropertyDescriptors()) {
if (pd.getPropertyType().equals(FileBean.class)) {
fieldName = pd.getName();
break;
}

} catch (Throwable t) {
}
// add validation error

double max = (double) exception.getMaximum() / 1024;

You are creating the hacked up StripesRequestWrapper, but you're
never using it. Also, we changed how localizable messages are
looked up and that would cause an NPE with the code you have. I've
done a little more hacking on it, and the following code will work
if you make the wrapper final.
// redirect back to referer
return new RedirectResolution(path) {
@Override
public void execute(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
ExecutionContext exec = new ExecutionContext();
exec.setActionBean(actionBean);
exec.setActionBeanContext(context);
DispatcherHelper.fillInValidationErrors(exec);
super.execute(wrapper, response);
}
}.flash(actionBean);
