完全按照WaitingTask.j写的，为什么执行时出错？

liaozm

我想做一个类似待办任务的东西，按照WaitingTask.j编写了程序，配置了widget.xml
但执行的时候总是提示com.justep.biz.client.Action@1cd2034java.lang.IllegalArgumentException！

程序如下：public class WaitingTask implements JProcessor {        public static final String PROCESS = "/SA/task/taskView/taskViewProcess";
        public static final String ACTIVITY = "mainActivity";
        private static final String VIEW = "/UI/SA/task/taskView/waitingTasksView.xhtml";
        private static final String QUERY_WAIT_TASK_ACTION = "queryWaitTaskAction";
       
       
        public void execute(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
                Document taskDoc = queryWaitTasks(request);
                Document viewDoc = getView();
                String executor = NetUtils.getExecutor(request);
                if (executor == null){
                        executor = "";
                }
                taskDoc.getRootElement().addElement(NetUtils.EXECUTOR).addText(executor);
                Map<String, Object> params = new HashMap<String, Object>();
                Document result = UIUtils.xslt(viewDoc, taskDoc, params);
                UIUtils.ouputXHTML(request, response, result);
        }
       
        private Document getView(){
                try {
                        String path = FileSystemWrapper.instance().getRealPath(VIEW);
                        SAXReader reader = new SAXReader();
                        return reader.read(new File(path));
                } catch (Exception e) {
                        throw new UIException(e.getMessage(), e);
                }
        }       
       
        private Document queryWaitTasks(HttpServletRequest request){
                Action action = new Action();
                action.setProcess(PROCESS);
                action.setActivity(ACTIVITY);
                action.setName(QUERY_WAIT_TASK_ACTION);
                action.setExecutor(NetUtils.getExecutor(request));
                action.setExecuteContext(NetUtils.getExecuteContext(request));               
                String bsessionID = NetUtils.getBSessionID(request);
                String language = NetUtils.getLanguage(request);
                ActionResult ar = ActionEngine.invokeAction(action, ActionUtils.XML_CONTENT_TYPE, bsessionID, language, null);

                return (Document)ar.getContent();
        }
       
}

错误如下：

错误信息看是应该是调用action时错误的可以跟一下代码看看

hecr

从错误来看，是调用queryPB_RiskPromptAction时，参数个数不一致导致的;
检查一下queryPB_RiskPromptAction的定义与调用点， 看看参数是否一致。

结贴，是参数错了
