JSF 2 Composite:ActionSource在ui:repeat中公开commandButtons [英] JSF 2 composite:actionSource exposing commandButtons in ui:repeat

问题描述

在我的复合组件中，我有一个ui:repeat，其中除了其他静态内容外，还具有一个命令按钮，如下所示:

In my composite component, I have a ui:repeat that has, among other static things, a command button, like this:

 <ui:repeat var="article" value="#{cc.attrs.articleList}">
     <strong>Aricle: #{article}</strong>
     <h:commandButton id="addToFavs" value="Subscribe" binding="..." type="..." >
         <f:setPropertyActionListener value="#{article}" target="..." />
     </h:commandButton >
 </ui:repeat>

现在，我想在复合界面中公开此事件，以便在我的页面中，我可以附加事件侦听器并绑定f:ajax.

Now, I'd like to expose this event in the composite interface, so that in my page, I may attach event listeners and tie in f:ajax.

如果它不在ui:repeat之外(即仅存在一个这样的按钮)，那将是非常容易的，就像这样:

Had it been outside of ui:repeat (i.e., there existed only one such button), that would have been quite easy, like this:

<composite:interface>
  <composite:actionSource name="addToFavs" targets="#{cc.clientId}:addToFavs" />
  <composite:clientBehavior name="ajax" default="true"
                              event="action" targets="#{cc.clientId}:addToFavs"/>
</composite:interface>

但是在这种情况下失败了，因为该ID没有一个组件( addToFavs )，而是一堆组件.您知道我应该如何在界面中显示这些按钮吗?

But that fails in this case, because there's no one component by that ID (addToFavs), but rather a bunch of them. Do you know how should I expose these buttons in the interface?

此致

推荐答案

以我的最佳猜测来更新此帖子，以防万一有人想知道我是否可以实现:

Updating this post with my best guess, just in case someone wants to know if I could achieve it:

不，我做不到.看来我们做不到.我们只能公开组件作者事先知道相对于复合组件的ID的组件.

No I couldn't do it. Looks like we can't do it. We can only expose components whose IDs relative to the composite component are known to the component author apriori.
