警告：尽管 <p:message autoUpdate="true">，仍有一些未处理的 FacesMessages

Question

大家好，我正在 eclipse 上开发 JSF+PrimeFaces 项目，我收到以下警告消息：

WARNING: There are some unhandled FacesMessages, this means not every FacesMessage had a chance to be rendered.
These unhandled FacesMessages are: 
- The email field is required
- The password field is required

这里是我表单的源代码

<p:tab title="#{msg['stu']}">
                    <h:panelGrid columns="2" cellpadding="10">
                        <div class="card container">
                            <h:form id="formStudent">
                                <fieldset style="width: 300px; margin-left: 20px;">
                                    <legend>
                                        <h:outputText value="#{msg['page.login.student']}" />
                                    </legend>

                                    <div class="p-field p-grid">
                                        <label for="email" class="p-col-fixed" style="width: 100px"><h:outputText
                                                value="#{msg['email']}" /></label>
                                        <div class="p-col">
                                            <p:inputText id="emailStudent" required="true"
                                                requiredMessage="#{msg['required.email']}"
                                                value="#{studentMB.student.email}" type="email" />
                                            <p:message autoUpdate="true" for="emailStudent" />
                                        </div>
                                    </div>

                                    <div class="p-field p-grid">
                                        <label for="password" class="p-col-fixed" style="width: 100px"><h:outputText
                                                value="#{msg['password']}" /></label>
                                        <div class="p-col">
                                            <p:password id="passwordStudent"
                                                requiredMessage="#{msg['required.password']}"
                                                value="#{studentMB.student.password}" toggleMask="true"
                                                redisplay="true" />
                                            <p:message autoUpdate="true" for="passwordStudent" />
                                        </div>
                                    </div>

                                    <p:commandButton value="#{msg['login']}"
                                        styleClass="ui-button-raised p-mr-2 ui-button-primary"
                                        action="#{studentMB.login}" />
                                    <br />
                                </fieldset>
                            </h:form>
                        </div>
                    </h:panelGrid>
                </p:tab>

请问我该如何解决这个问题？谢谢

应删除 p:message 上的 autoUpdate 属性，并替换为：

<p:message for="input-field-id" >
    <p:autoUpdate />
</p:message>

警告：尽管 <p:message autoUpdate="true">，仍有一些未处理的 FacesMessages
