动态ui：包括ui内部：重复。有简单的解决方案吗？ [英] Dynamic ui:include inside ui:repeat. Is there a simple solution?

问题描述

我想动态选择一个facelet来渲染我的数据列表中的一些项目。第一次尝试是：

I want to dynamically pick a facelet to render some item in my data list. The first try would be:

<ui:repeat value="#{panels}" var="panel">
  <ui:include src="#{panel.facelet}">
</ui:repeat>

但是由于ui：include的src过早评估，因此无法正常工作。 facelet信息是真正动态的，所以我不能使用c：forEach（不是真的建议与facelets混合使用）。我想这一切都归结为找到一个基于ui的组件：包含替代品。

But it won't work since src of ui:include is evaluated too early. The facelet information is truly dynamic, so I cannot use c:forEach (not really recommended to mix with facelets either). I guess it all boils down to finding a component based ui:include alternative.

是否有这样的事情或我需要自己编写？

Is there such thing or I need to write my own?

推荐答案

c：forEach会解决它，你为什么不能使用它？

c:forEach will solve it, why can't you use it?
