http://nagoya.apache.org/bugzilla/show_bug.cgi?id=26639 Multipart request parameters lost after validation failure Summary: Multipart request parameters lost after validation failure Product: Struts Version: 1.1 Final Platform: PC OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: Controller AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] This happens when the input attribute of an action is set to another .do instead of a jsp page. The form has enctype set and after validation failure request becomes empty. Here is how I solved this in RequestProcessor: Note that getAllParametersForMultipartRequest() was copied from RequestUtils. -------------------------------------------------------- protected boolean processValidate(HttpServletRequest request, HttpServletResponse response, ActionForm form, ActionMapping mapping) throws IOException, ServletException { if (form == null) { return (true); } // Was this request cancelled? if (request.getAttribute(Globals.CANCEL_KEY) != null) { if (log.isDebugEnabled()) { log.debug(" Cancelled transaction, skipping validation"); } return (true); } // Special handling for multipart request if (form.getMultipartRequestHandler() != null) { // Handle repopulation of parameters. MultipartRequestWrapper wrapper = (MultipartRequestWrapper) request; if(request.getAttribute(PARSED_MULTIPART_REQUEST) != null){ Map params = (Map)request.getAttribute (PARSED_MULTIPART_REQUEST); // Populate fresh request. Iterator iter = params.keySet().iterator(); while (iter.hasNext()) { String key = (String) iter.next(); Object value = params.get(key); if(value instanceof String[]){ String[] val = (String[]) value; if(val.length > 0){ System.out.println ("XXXXXXXX Setting parameter " + key + " to " + val[0]); wrapper.setParameter (key, val[0]); } } } } else{ // Retrive form values and put into properties. Map multipartParameters = getAllParametersForMultipartRequest( request, form.getMultipartRequestHandler()); request.setAttribute(PARSED_MULTIPART_REQUEST, multipartParameters); } } return super.processValidate(request, response, form, mapping); } --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
