我已经完全更改了代码。但活跃指数仍显示出问题。有时它会被呼叫，有时它不会。下面的xhtml代码出了什么问题？

更新：@raggs我在activeindex中遇到了一些问题。在activeindex和所有东西都开始工作后，我开始比较我的代码，以了解出了什么问题。现在，当我将输入字段和其他组件中的required="false"更改为required="true"时，activeindex将无法再次工作。

我有很多选项卡和手风琴选项卡。当我为一个选项卡的每个组件制作required="false"时，activeindex起作用。将全部更改为required="true"会导致activeindex不起作用，但如果仅为一个标签的组件更改为required="false"，activeindex也可以。
如果<p:tabView在<h:form中，则会更新_activeIndex。如果<p:tabView不在<h:form中，则_activeIndex不会更新。这可以在使用Firebug的POST中看到。
据我所知，_activeIndex和_activetab应该和TabView组件具有相同的值。
我在多个选项卡中使用以下代码，每个选项卡中都有不同的形式：
public void tabIsChanged(TabChangeEvent event) {
//This code was taken directly from TabViewRenderer.
FacesContext context = FacesContext.getCurrentInstance();
Map<String, String> params = context.getExternalContext().getRequestParameterMap();
TabView tabView = (TabView) event.getComponent();
String activeIndexValue = params.get(tabView.getClientId(context) + "_tabindex");
//this.activeTab = Integer.parseInt(activeIndexValue);
this.myCurrentATab = Integer.parseInt(activeIndexValue);
}
也许这是你的解决方案。
如果您想控制活动选项卡，这是一种方法：
<p:tabView>
<p:ajax event="tabChange" listener="#{bean.onTabChange}"/>
<p:tab title="TitleTabOne"></p:tab>
<p:tab title="TitleTabTwo"></p:tab>
<p:tab title="TitleTabThree"></p:tab>
</p:tabView>
public void onTabChange(TabChangeEvent event) {
TabView tabView = (TabView) event.getComponent();
int activeTabIndex = tabView.getActiveIndex();
System.out.println(activeTabIndex);
if(activeTabIndex == 1){
// Your tab is active, do something...
}
}
我希望这能帮助。。。
祝你好运！
简单地说，将tabView与activeIndex一起使用，并将代码添加到tabView中，即可解决如下问题：
<p:tabView id="tv" activeIndex="#{yourBean.activeTabIndex}">
<p:ajax event="tabChange" process="@this"/>
</p:tabView>
如果没有tabChangeEvent，activeIndex将无法工作。
