我有一段代码如下
<p:growl id="noti-growl"/>
<h:form id="login-form">
<p:panel>
<h:commandButton value="Đăng nhập" class="button-login" action="index">
<f:ajax execute="@form" render="noti-growl"/>
</h:commandButton>
</p:panel>
</h:form>
我收到如下错误
<f:ajax> contains an unknown id 'noti-growl' - cannot locate it in the context of the component j_idt9
请给我解释一下?感谢您的帮助
