Primefaces p:树在v4中工作成功，在v5、v5.1、5.2、5.3和6中工作失败

我使用MojaraJSF2.2和PrimeFaces4、Wildfly作为web服务器和EclipseNeon作为IDE开发了一个web应用程序。而且效果很好。当我尝试迁移到Primefaces 5时，一切正常，除了p:tree未能触发任何选择事件。v5.1、5.2、5.3和6也出现了同样的情况。 因此，如果您有任何帮助，我们将不胜感激

下面是p:树代码片段：

<h:form id="barForm">
                    <p:tree id="treeSingle" value="#{treeBackBean.root}" var="node"
                        selectionMode="single" selection="#{treeBackBean.selectedNode}"
                        dir="rtl" style="height: 100%; width: 200px;">
                        <p:ajax event="select" listener="#{treeBackBean.onNodeSelect}" />
                        <p:treeNode>
                            <h:outputLabel value="#{node}" />
                        </p:treeNode>
                    </p:tree>
                </h:form>

}

我还使用AppUtil从属性文件中获取属性值

请改进你的标题。PrimeFaces展示区也很有效。找到differences@Kukeltje我从PrimeFaces showcase学习，我知道在那里工作很好。但我不工作，至少在v4之后的任何最新版本，我不知道为什么。无论如何，谢谢，我很感激。我在xhtml正文中使用了ajaxStatus，当我将p:tree的ajax选择事件全局属性设置为false时，它似乎以某种方式阻止了p:tree的ajax选择事件。它适用于所有版本。但这种方式会产生很多其他问题，因为它会禁用触发其他操作……例如：commondButton和commondLink停止工作。您可以编辑您的问题。使代码更具可读性
