Question

当我尝试使用可滚动的TreeTable（但不会使用不可滚动的TreeTable）组件时，我收到了这个奇怪的错误。

enter image description here

如果我添加

，该组件在点击时不会折叠或展开

style="margin-top:0" scrollable="true" scrollHeight="150"

到p：treeTable组件。

如果我删除它，它就像一个魅力。

尝试了两个主要的第4和第5社区。

使用mojarra 2.2.0在tomcat 7上运行。（由eclipse添加），Oracle Java 7。

尝试在firefox 30.0，chrome 35和IE 11上运行。

看起来像是一些弃用的JQuery方法，但是为什么第4和第5个方面会用错误的JQuery分发它们的单个jar？

听起来我在这里遗漏了一些东西。我该怎么做才能解决这个问题？

我使用Eclipse Kepler RC1创建了一个动态Web项目，这里是配置信息（非常香草）

$。浏览器最近在jquery中被弃用了。要使用已弃用的函数，请使用jquery migrate plugin

该插件可恢复已弃用的功能和行为，以便更旧代码仍然可以在jQuery 1.9及更高版本上正常运行。
