c:forEach未遍历TabView中的列表 [英] c:forEach not iterating through list in a TabView

问题描述

我一直在尝试使用c:forEach标记遍历选项卡列表(我自己的自定义选项卡对象).但是，当我运行代码时，选项卡没有显示.该页面没有标签.

I have been trying to iterate through a list of tabs (my own custom tab object) by using c:forEach tag. But when I run the code, the tabs are not getting displayed. The page has no tabs.

当我调试代码时，我发现c:forEach项目中的列表对象的getter方法没有被调用.请参考下面的xhtml代码:

When I debugged the code, I found that the getter method for the list object in the c:forEach items is not getting called. Please refer the below xhtml code:

<p:tabView id="tabView" dynamic="true" cache="false">   
       <p:ajax event="tabChange" listener="#{tabsController.onTabChange}" />

       <c:forEach  items="#{menusController.tabs}" var="customTab" varStatus="loop">
        <p:tab title="#{customTab.title}" >
            <f:subview id="tab_#{loop.index}">
                   <ui:include src="#{customTab.pageName}" />
            </f:subview>
            </p:tab>
         </c:forEach>
       </p:tabView>

我试图遵循本文中的解决方案 JSF动态地在"ui:include src ="#{bean.pagePath}" 中包含src，但仍然无法正常工作.

I tried to follow the solution in this post JSF dynamically include src in "ui:include src="#{bean.pagePath}" but still it didn't work.

推荐答案

您不应混用JSP和JSF标记，c:forEach在JSF解析器之前执行，而应使用ui:repeat.

You should not mixing JSP and JSF tags, c:forEach is executing before JSF parser, instead use ui:repeat.
