Question

我有primefaces命令按钮多次更新问题。命令按钮位于表单内，而数据表不是。

我试过了：

update=":datalist1,form1" 
update=":datalist1 form1" 
update="datalist1 form1"
update=":#{p:component('datalist1')},form1"

form1每次更新但仍然没有更新数据表

Version info:
primefaces: 5.3 
jsf: org.glassfish 2.3.0-m04
spring: 4.2.3
and I use cdi for controller beans

班级：

    public void setPersonel(Personel personel) {
        this.personel = personel;
    }

    public void createPersonel(){
        System.out.println("Personel adding..");
        personelService.create(personel);
        personel=new Personel();
        System.out.println("Personel added");
    }

}

我研究过primefaces命令按钮更新，但所有建议都不适用于我。提前谢谢

Answer 1

在我看来，新创建的人员从未添加到列表中。所以你必须例如说

personels.add(personel);

或

personels=personelService.findAll();

在createPersonel（）中，或将personel设置为null并在getPersonels（）中执行延迟加载。

Primefaces命令按钮不更新数据表
