我有一个我无法解决的问题。当我打开JSF选项卡并尝试单击按钮时，页面无效。

当我删除ui:composition标记并将所有代码插入一个页面时，按钮正在工作。

正如您在其中一条评论中指出的那样，您无法使用嵌套表单。您需要重新构建布局。将外部表单放在<ul>：
<h:panelGroup id="tabs" layout="block">
<h:form prependId="false">
<ul>
...
</ul>
</h:form>
<c:forEach items="#{DatacenterProfileController.tabs}" var="tab">
...
</c:forEach>
</h:panelGroup>
其余的代码应该没问题。通过这种方式，您可以避免使用嵌套表单。
