使用PrimeFaces“的RequestContext更新另一个页面的组件 [英] Using PrimeFaces' RequestContext to update a component in another page

问题描述

我发现PrimeFaces的RequestContext＃更新我发现它非常有用。

I've discovered PrimeFaces' RequestContext#update and I've found it very useful.

现在我希望它更新一个组成部分，这不是谁被称为豆在页面上。

Now I want it to update a component that's NOT on the page who called the bean.

有没有办法告诉给的RequestContext＃更新这是需要更新的部分是另一页上？

Is there any way to tell to RequestContext#update that the component that need to be updated is on another page?

是这样的： RequestContext.getCurrentInstance（）更新（downloads.xhtml，：downloadPanel）

推荐答案

如果您导航回正是页面时操作方法结束这是唯一可能的。这使得否则没有意义反正作为的RequestContext 仅适用于当前请求。

That's only possible if you navigate back to exactly that page when the action method finishes. It makes otherwise no sense anyway as the RequestContext applies to the current request only.
