在dataList中我显示记录并给出编辑和删除选项， 删除时我需要检查我的要求取决于我需要删除记录， 但删除DataList后没有更新。
你能解决我的问题......

答案 0 :(得分：0)
我在top中给出的是正确的，但是java方法存在问题。
删除，我给了一个java方法“action =”＃{appraisalComponent.deleteSection（appraisalComponent.selectedSec）}“”
在返回一个值的java中，如下所示
public String deleteSection (int secId) {
String temp ;
// some code
return temp;
}
但我们应该只提供如下的无效方法
public void deleteSection (int secId) {
}
我改变了这个，现在我的代码工作正常。 不管怎样，谢谢。 ：）
