我在使用 primefaces 的 dataTable 时遇到了一个奇怪的行为。当我在列表中添加新行并且数据表刷新时，标题会重复；因此，添加第一行后，标题显示 2 次，第二行后显示 4 次，依此类推。我试图删除过滤选项，但我仍然得到相同的行为。有人遇到过同样的问题吗？我正在使用 Primefaces 4.0 和 Tomcat 7。

提前感谢任何可以帮助我的人，并为我糟糕的英语感到抱歉。

这是我的代码： index.xhtml 页面包括我的 motionList.xhtml 页面，其中包含 dataTable：

解决删除 scrollable="true" 或更改为 scrollable="false"
