After tracing the code, i found that the kruntime changed to null suddenly... kruntime is set previously. but it changed to null when calling getProcess() To test it: Add the following to org.jboss.bpm.console.server.ProcessMgmtFacade.java in jbpm-gwt-console-server   @POST   @Consumes("multipart/form-data")   @Path("instance/{id}/data")   public Response setInstanceData(                       @Context                       HttpServletRequest request,                       @PathParam("id")                       String instanceId   )   {             try {                 ServletFileUpload upload = new ServletFileUpload();                 FileItemIterator fileIterator = upload.getItemIterator(request);                 while (fileIterator.hasNext()) {                     FileItemStream item = fileIterator.next();                     log.info("Setting Process instance data: Content-Type: " + item.getContentType() + " Name: " + item.getFieldName());                     Map<String, Object> data = new HashMap<String, Object>();                     if (item.getContentType() == null){                         String s = IOUtils.toString(item.openStream());                         data.put(item.getFieldName(), s);                     } else {                               File f = File.createTempFile("file-", "");                         IOUtils.copy(item.openStream(), new FileOutputStream(f));                         data.put(item.getFieldName(), f.getCanonicalPath());                     }                     getProcessManagement().setInstanceData(instanceId, data);                 }             } catch (Exception e) {           log.info("cannot set instance data", e);             }       ProcessInstanceRef instance = getProcessManagement().getProcessInstance(instanceId);       return createJsonResponse(instance);   } then post something to gwt-console-server/rs/process/instance/{yourinstanceid}/data NullPointerException @ setInstanceData -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/620497#620497] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
