版本：primeface3.5

发生在什么时候：

页面选择子节点后，再次进行请求操作，比如查询、数据下载等

Apparently during render Response phase, it was always trying to look in the first treeNode even though the node that we are currently working is from second or subsequent treeNodes.

解决参考：

1、为了解决树的再次选择，需要在操作之前执行更新树

参考：

2、解决提交报异常，修改源代码。参考：
