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
DecimalFormat format = new DecimalFormat("0.00");
double max = (double) exception.getMaximum() / 1024;
double posted = (double) exception.getPosted() / 1024;
context.getValidationErrors().add(fieldName,
new LocalizableError("error.file.too.large",
format.format(max), format.format(posted)));
// redirect back to referer
return new RedirectResolution(path) {
@Override
public void execute(HttpServletRequest request,
HttpServletResponse response) throws ServletException,
IOException {
ExecutionContext executionContext = new
ExecutionContext();
executionContext.setActionBean(actionBean);
executionContext.setActionBeanContext(context);
DispatcherHelper.fillInValidationErrors(executionContext);
super.execute(wrapper, response);
}
}.flash(actionBean);
}

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);
