JSF监听器不叫嵌套的UI里面：重复 [英] jsf listener not called inside nested ui:repeat

问题描述

我有使用问题 UI：重复互相嵌套，我想请一个听众。我也曾尝试 C：的forEach 代替，但得到了同样的问题。

。

有关证明我已经简化了code到问题的问题。 有两个按钮，首先第一个界面内：重复，调用成功的一个简单的监听器。第二个按钮是嵌套的UI内：重复元素，应该调用相同的侦听器作为第一个按钮，但监听器永远不会被调用

你能告诉我什么是错呢？

 ＆LT; D​​IV＆GT;
    ＆LT; UI：重复VAR =testList值=＃{testBean.testList}＆GT;
        ＆LT; H：的commandButton值=测试1＆GT;
            //调用该侦听器，如果我点击这个按钮
            ＆LT; F：Ajax事件=点击执行=@这个监听器=＃{testBean.testListener}/＆GT;
        ＆LT; / H：的commandButton＆GT;
        ＆LT; UI：重复VAR =nestedList值=＃{testList.nestedList}＆GT;
            ＆LT; H：的commandButton值=测试2＆GT;
                //监听器就不会被调用，如果我点击这个按钮
                ＆LT; F：Ajax事件=点击执行=@这个监听器=＃{testBean.testListener}/＆GT;
            ＆LT; / H：的commandButton＆GT;
        ＆LT; / UI：重复＆GT;
    ＆LT; / UI：重复＆GT;
＆LT; / DIV＆GT;
 

解决方案

这是一个已知的Mojarra问题涉及到打破＆LT状态管理;用户界面：重复＆GT; 。特别是这个问题被报告为问题1817 并固定，因为Mojarra 2.1.15。

升级您的Mojarra版本。这是目前的已经在2.1.19。

I have a problem using ui:repeat nested in each other where I'd like to call a listener. I have also tried c:forEach instead, but got the same problem.

For demonstrating the problem I have simplified the code to the problem. There are two buttons, the first inside the first ui:repeat, calling successful a simple listener. The second button is inside the nested ui:repeat element, should call the same listener as the first button, but the listener is never called.

Can you please tell me whats wrong with this?

<div>
    <ui:repeat var="testList" value="#{testBean.testList}">
        <h:commandButton value="test1">
            // the listener is called if I click this button
            <f:ajax event="click" execute="@this" listener="#{testBean.testListener}" />
        </h:commandButton>
        <ui:repeat var="nestedList" value="#{testList.nestedList}">
            <h:commandButton value="test2">
                // the listener will not be called if I click this button
                <f:ajax event="click" execute="@this" listener="#{testBean.testListener}" />
            </h:commandButton>
        </ui:repeat>
    </ui:repeat>
</div>

解决方案

This is a known Mojarra issue related to broken state management of <ui:repeat>. Specifically this issue is reported as issue 1817 and fixed since Mojarra 2.1.15.

Upgrade your Mojarra version. It's currently already at 2.1.19.
