不显示带有clientId的消息

Question

我遇到以下问题-我尝试将一些错误消息从后端bean添加到我的JSF页面。此消息与客户端ID一起添加。当我尝试添加不带客户端ID的消息时，一切正常。我必须补充说，同一bean被多个页面使用。该页面如下所示：

<ui:composition xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
    xmlns:p="http://primefaces.org/ui"
    xmlns:pt="http://xmlns.jcp.org/jsf/passthrough"
    template="/WEB-INF/templates/blank.xhtml">

    <ui:define name="content">
        <p:messages id="messages" showDetail="true" closable="true">
            <p:autoUpdate/>
        </p:messages>

        <h:form id="changePassword" pt:autocomplete="off">
            <h:panelGroup layout="block" styleClass="dialogForm">
                <h:panelGrid styleClass="datatable">
                    <h:panelGroup>
                        <p:password id="oldpassword" value="#{ChangePwdBean.oldPassword}"
                            styleClass="requested" redisplay="false" required="true"
                            tabindex="1" />
                        <p:message for="oldpassword"/>
                    </h:panelGroup>

                    <h:panelGroup>
                        <p:password id="password" value="#{ChangePwdBean.password}"
                            styleClass="requested" redisplay="false" required="true"
                            tabindex="2"
                            validator="#{ChangePwdBean.validatePassword}" />
                        <p:message for="password"/>
                    </h:panelGroup>

                    <h:panelGroup>
                        <p:password id="passwordVerify" styleClass="requested"
                            redisplay="false" required="true" tabindex="3"
                            value="#{ChangePwdBean.passwordVerify}"                         
                            validator="#{ChangePwdBean.validatePasswordVerify}" />
                        <p:message for="passwordVerify"/>
                    </h:panelGroup>
                </h:panelGrid>
            </h:panelGroup>

            <h:panelGroup layout="block" styleClass="divLoginButton">
                <p:commandButton id="btnLogin" action="#{ChangePwdBean.changePwd}"
                    value="#{appl['buttons.change.password']}" 
                    styleClass="buttonChangePwd" tabindex="4" ajax="false"
                    style="margin-right: 3px;"
                    update="@form">
                </p:commandButton>

                <p:commandButton id="btnLogout" value="#{appl['buttons.cancel']}"
                    action="toLogout" immediate="true" styleClass="buttonCancel" />
            </h:panelGroup>
            <p:focus for="oldpassword" />
        </h:form>

    </ui:define>
</ui:composition>

后端bean中向页面添加消息的代码如下：

public static void addErrorMessage(final String clientId, final String message, final Object[] param) {
    final UIComponent uiComp = setComponentToInvalid(clientId);
    FacesContext.getCurrentInstance().addMessage(uiComp != null ? uiComp.getClientId() : null, new FacesMessage(FacesMessage.SEVERITY_ERROR, message, StringUtils.EMPTY));
}

protected static UIComponent setComponentToInvalid(final String clientId) {
    final UIComponent uiComponent = getUIComponent(null, clientId);
    if (uiComponent != null && uiComponent instanceof UIInput) {
        ((UIInput) uiComponent).setValid(false);
    }
    return uiComponent;
}

并对此方法进行示例调用：

addErrorMessage("password", "Password is too short!", new Object[] {});

在此先感谢您的帮助！
