我有一个使用Java 7，PrimeFaces 5（JSF），Tomcat 7开发的Web应用程序。不久前，用户报告了生产环境中的一个缺陷，他点击的所有内容都导致页面刷新。我无法重现它然后我忘了它...但是现在我只是重现了这个问题，这是第一次在我的本地机器上运行应用程序。 我点击的任何按钮，触发ajax请求，后面会有页面刷新。我尝试重新启动tomcat并使用CMD + SHIFT + R清除Chrome的缓存，但我仍然可以重现此问题。
我可以在Google Chrome上重现，但不能在Firefox和Safari上重现。我从Firefox和Chrome的开发者工具中打开了网络选项卡来比较请求...但我仍然无法理解......有没有人知道可能会发生什么？
我将在以下关闭事件的网络活动下面提供：
<p:panel id="myPanel" widgetVar="myPanelVar" closable="true">
<p:ajax event="close" listener="#{myBean.changeSomeVariables}" />
<h:outputText value="Example panel"/>
<a onclick="PF('myPanelVar').close();"><span class="ui-icon ui-icon-closethick"></span></a>
</p:panel>
Firefox的网络活动（正常工作）：
