Question

当用户在第一个selecOneMenu上触发事件时，我想生成第二个selecOneMenu内容，但它不起作用。

这是face-config.xml中的导航规则

 <navigation-rule>
     <from-view-id>/index.xhtml</from-view-id>
        <navigation-case>
            <from-action>#{contact_.inscription_fournisseur}</from-action>
            <from-outcome>success</from-outcome>
            <to-view-id>xhtml/Inscription_user.xhtml</to-view-id>
        </navigation-case>
    </navigation-rule>

这是我的索引页面：当我点击 S'inscrire 时，它会启动第一个列表并将我重定向到Inscription_user.xhtml

}

有一个解决方案是从contact_ bean类的inscription_fournisseur（）方法中删除方向列表中的初始化，并将其设置在organisation_ bean类的默认构造函数中，在这种情况下它可以工作，但我不知道我更喜欢这个解决方案，我更喜欢第一个场景，请帮助我。

Answer 1

您使用错误的命名空间<f:ajax>应为<p:ajax>
相反，您应更改update以更新所需内容，并在listener定义的方法中设置所选值，以更改其他selectMenu的数据

请参阅showcase example

PrimeFaces p：ajax event =“change”未被触发
