action中如何获取流水号以及刷新失败问题

736261089

请问action中如何获取流水号，写给另一模块的接口，进行新增数据。另外有个问题，button指向自定义的action，界面停一段时间不点击后，第一次点击会出现刷新失败，再点击正常，很容易复现，请问有什么合适的优化方式吗

The last packet successfully received from the server was 561,171 milliseconds ago.  The last packet sent successfully to the server was 561,181 milliseconds ago.

这个错误是数据库报错了http://docs.wex5.com/bex5-deploy-question-list-4011/

已修改，谢谢。另外java代码中是否有类似nextSeq()的方法

BizUtils.getNextSequence(String key);
