Tapestry4之组件ExternalLink

最近发现，ExternalLink组件原来还可以这么用，通过绑定renderer,可以在page中定义新弹出页的属性。

<component id="viewDetails" type="ExternalLink">
        <binding name="page" value="'admin/AdminViewStudentInfo'"/>
        <binding name="parameters" value="components.rows.tableRow.userId"/>
        <binding name="renderer" value="beans.popupLinkRenderer"/>
    </component>

<bean name="popupLinkRenderer"
        class="org.apache.tapestry.contrib.link.PopupLinkRenderer">
        <set name="windowName" value="'StudentInfo'"/>
        <set name="features"
            value="'top=10,left=10,width=830,height=700,scrollbars=yes,resizable=yes'"/>
    </bean>
