我觉得panelGroup中会被吞噬，因为只有一个组件中。也许JSF优化它。

I think the panelGroup will be swallowed since there is only one component inside. Maybe jsf optimizes it.

再有就是只有 H：的outputText 离开这的 未实现部分的这是需要的，获取阿贾克斯附加的组件javax.faces.component.behavior.ClientBehaviorHolder 接口。

Then there is only the h:outputText left and this component doesn't implement the javax.faces.component.behavior.ClientBehaviorHolder interface which is required for a component that gets ajax attached.

您可以使用 H：outputLink的或者 H：。outputLabel 而不是
