我有一个问题需要尽快解决，需要你们帮忙。 我有一个带有selectBooleanCheckbox和列过滤的数据表和一个删除按钮（ajax =“false”）。当页面加载时，我按此顺序有五条记录，记录1，记录2，记录3，记录4，记录5.之后，我过滤3.然后我选中复选框并单击删除。但记录1被删除了。
先谢谢！

使用Primefaces select（单个和多个）内置函数。
基本
http://www.primefaces.org/showcase/ui/datatableRowSelectionByColumn.jsf
单
http://www.primefaces.org/showcase/ui/datatableRowSelectionSingle.jsf
多个
http://www.primefaces.org/showcase/ui/datatableRowSelectionMultiple.jsf
即时
http://www.primefaces.org/showcase/ui/datatableRowSelectionInstant.jsf
广播/复选框（我认为这是解决您问题的一种方法）
