public void signal(ActivityExecution activityExecution, String signalName,
			Map<String, ?> parameters) throws Exception {
		
		ExecutionImpl execution = (ExecutionImpl) activityExecution;
		ExecutionService executionService = EnvironmentImpl
				.getFromCurrent(ExecutionService.class);
		TaskService taskService = EnvironmentImpl.getFromCurrent(TaskService.class);
		String executionId = activityExecution.getId();
	
		Map<String, Object> variables = executionService.getVariables(executionId, executionService
				.getVariableNames(executionId));

		//获取子任务
		Task subTask = (Task) parameters.get("subTask");
		taskService.completeTask(subTask.getId());//结束子任务
		
		//收集会签意见
		String countersignAgree = (String) parameters.get("countersignAgree");//会签意见内容
		Conclusion conclusion = (Conclusion) parameters.get("conclusion");//会签选择
		 signalName=(String)parameters.get("signalName");
		String assignee = subTask.getAssignee();//会签人
		
		//更新集合信息
		CountersignInfo countersignInfo = (CountersignInfo) variables.get(subTask.getActivityName() + "_COUNTERSIGN_INFO");
		
		Map<String, CountersignUser> users = countersignInfo.getUsers();
		CountersignUser countersignUser = users.get(assignee);
		countersignUser.setConclusion(conclusion);
		countersignUser.setCountersignAgree(countersignAgree);
		
		boolean allSign = true;
		
		//遍历是否会签完毕
		for (CountersignUser item : users.values()) {
			if(item.getConclusion() == Conclusion.NOSTART){
				allSign = false;
			}
		}
		
		countersignInfo.setAllSign(allSign);
		//如果会签完毕，计算结果
		if(allSign){
			countersignInfo.calculate();
			String agree = "同意";
			//如果结果为否决
			if(countersignInfo.getConclusion() == Conclusion.DENED){
				agree = "不同意";
			}
			variables.put("agree", agree);
			//更新集合信息
			signalName="";
			executionService.setVariables(executionId, variables);
			if(signalName!=null&&!signalName.equals(""))
			{
				activityExecution.take(signalName);//执行下一步
			}
			
			return;
		}
		
		//否则继续等待
		execution.waitForSignal();
	}

这个方法中的signalName的值如何获取？

我的到的总是NULL！！！
