咆哮错误

Question

我有一个片段代码如下

<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>

我收到了如下错误

<f:ajax> contains an unknown id 'noti-growl' - cannot locate it in the context of the component j_idt9

请为我解释一下？谢谢你的帮助

将咆哮声放在你自己的形式中，如下所示

<h:form id="login-form">
   <p:growl id="noti-growl"/>
</h:form>

或者您应该通过将growl以不同的形式更新为全名：

 <h:form id = "growlForm">    
  <p:growl id="noti-growl"/>
 </form>

 <h:form id="login-form">
        <p:panel>
            <h:commandButton value="Đăng nhập" class="button-login" action="index" update = ":growlForm:noti_growl">

        </p:panel>
    </h:form>
