Jsf 以相同的咆哮声显示消息

如何使用咆哮在一个弹出窗口中显示所有验证消息，因为默认情况下，客户端上的每个验证消息都会创建新的弹出窗口

当然，我可以在服务器端进行验证，并将最终消息发送给growl，但是否可以在客户端进行验证

这里有一些代码：

<p:dialog id="chPwD" header="#{res['user.passwordDialogHeader']}" widgetVar="changePwV" closeOnEscape="true" resizable="false">
    <p:growl id="growl" showDetail="false" life="3000" />
    <h:panelGrid id="chPwPG" columns="1" cellpadding="1" transient="true">
        <h:panelGrid id="chPwPGi" columns="2" cellpadding="1">
            <p:outputLabel for="pwd0" value="#{res['user.oldPassword']}" />
            <h:panelGroup>
                <p:password id="pwd0" label="#{res['user.oldPassword']}" value="#{mngr.oldPassword}" required="true" style="width:250px;"/>
                <span style="display:inline-block;"><p:message for="pwd0"/><p:messages for="pwd0"/></span>
            </h:panelGroup>

            <p:outputLabel for="pwd1" value="#{res['user.newPassword']}" />
            <h:panelGroup>
                <p:password id="pwd1" label="#{res['user.newPassword']}" value="#{mngr.newPassword}" match="pwd2" required="true" style="width:250px;"/>
                <span style="display:inline-block;"><p:message for="pwd1"/></span>
            </h:panelGroup>

            <p:outputLabel for="pwd2" value="#{res['user.repeatNewPassword']}" />
            <h:panelGroup>
                <p:password id="pwd2" label="#{res['user.repeatNewPassword']}" value="#{mngr.newPassword}" required="true" style="width:250px;"/>
                <span style="display:inline-block;"><p:message for="pwd2"/></span>
            </h:panelGroup>
        </h:panelGrid>
    </h:panelGrid>
    <f:facet name="footer">
        <p:commandButton value="#{res['btn.apply']}" style="margin-right:20px;" update=":chPwPG" action="#{mngr.changeSelectedUserPassword}" oncomplete="handlePwChangeRequest(xhr, status, args)"/>
        <p:commandButton value="#{res['btn.cancel']}" onclick="changePwV.hide();" type="button"/>
    </f:facet>
</p:dialog>

你应该试试

，它对我有用
