JSF使用先前的请求结果更新视图

时间：2015-10-17 19:22:26

标签： maven jsf primefaces

更新我的项目以使用Primefaces 5.2，从5.0开始，我的所有更新都显示一个旧请求的数据。如果我单击一次commandLink两次，第一次单击在客户端没有执行任何操作，服务器执行action / actionListener，并且请求带有先前的数据而没有更改，第二次单击更新时带有第一个请求的结果。总是服务器完成工作，但JSF没有。

使用PrimeFaces 5.0，一切正常。

这是我的pom.xml配置：

    public List<Role> getList() {

    public void persist() {
