hi,
i think it is a bug in the FilterDispatcher. I change the Method
prepareDispatcherAndWrapRequest to this and now it works. Should i post it
to a bug-report? is there such a thing?
best regards
avajon
<pre>
protected HttpServletRequest
prepareDispatcherAndWrapRequest(HttpServletRequest request,
HttpServletResponse response) throws ServletException {
Dispatcher du = Dispatcher.getInstance();
// Prepare and wrap the request if the cleanup filter hasn't
already, cleanup filter should be
// configured first before struts2 dispatcher filter, hence when its
cleanup filter's turn,
// static instance of Dispatcher should be null.
if (du == null) {
Dispatcher.setInstance(dispatcher);
}
else {
dispatcher = du;
}
// prepare the request no matter what - this ensures that the
proper character encoding
// is used before invoking the mapper (see WW-9127)
dispatcher.prepare(request, response);
try {
// Wrap request first, just in case it is
multipart/form-data
// parameters might not be accessible through before
encoding (ww-1278)
request = dispatcher.wrapRequest(request,
getServletContext());
} catch (IOException e) {
String message = "Could not wrap servlet request with
MultipartRequestWrapper!";
LOG.error(message, e);
throw new ServletException(message, e);
}
return request;
}
</pre>
