如何在s:装饰中显示适当的信息(信息或警告)?

I am actually checking for availability of a login name and would like to show the info image or warn image with an appropriate message. Currently we get 2 error messages on non availability of a login name.

实际上，我正在检查登录名的可用性，并希望通过适当的消息显示信息图像或警告图像。目前，我们收到两个关于登录名不可用的错误消息。

            <s:decorate id="loginIdField" template="/layout/edit.xhtml">
                <ui:define name="label">Desired Login Name</ui:define>
                <a:region>
                    <h:inputText id="loginId" required="true" value="#{userHome.instance.loginId}"/>
                    <s:message warnStyle="color: red" infoStyle="color: green"/>
                    <div class="actionButtons">
                        <a:commandButton id="submit" value="Check Availability"
                            action="#{userHome.isUnique(userHome.instance.loginId)}" reRender="loginIdField"/>
                    </div>
                </a:region>
            </s:decorate>

Code to add appropriate messages in the bean.

在bean中添加适当消息的代码。

    if (!unique) {
        statusMessages
                .addToControlFromResourceBundle(
                        "loginId",
                        WARN,
                        "LoginIdNotUnique",
                        new Object[] { inputLoginId });
    } else {
        statusMessages.addToControlFromResourceBundle("loginId", INFO,
                "LoginIdUnique",
                new Object[] { inputLoginId });
    }

Maybe it's the template? Have you tried this without the template?

    <s:message warnStyle="color: red" infoStyle="color: green"/>
    </s:decorate>
    <div class="actionButtons">
        <a:commandButton id="submit" value="Check Availability"
            action="#{userHome.isUnique(userHome.instance.loginId)}" reRender="loginIdField"/>
