List apache tiles放置列表属性XML错误

我在tiles.xml中有这样的定义：

<definition name="t.base" template="/WEB-INF/tiles/base.jsp">
    <put-attribute name="title" value="SomeTitle" />
    <put-attribute name="menu" value="/WEB-INF/tiles/menu.jsp" />
    <put-attribute name="scripts" value="/WEB-INF/tiles/scripts.jsp" />
</definition>

<definition name="t.homepage" extends="t.base" preparer="com.blogspot.symfonyworld.lyricsbase.controller.TestViewPreparer">
    <put-list-attribute name="body">
        <add-attribute value="/WEB-INF/jsp/homepage.jsp" />
        <add-attribute value="/WEB-INF/tiles/footer.jsp" />
    </put-list-attribute>
    <put-attribute name="title" value="lyricsBase : home of lyrics" />
    <put-attribute name="view" value="homepage" cascade="true" />
</definition>

我不知道哪里出了问题-XML语法似乎是正确的。

元素必须位于定义的末尾，如下所示：

<definition name="t.homepage" extends="t.base" preparer="com.blogspot.symfonyworld.lyricsbase.controller.TestViewPreparer">
    <put-attribute name="title" value="lyricsBase : home of lyrics" />
    <put-attribute name="view" value="homepage" cascade="true" />
    <put-list-attribute name="body">
        <add-attribute value="/WEB-INF/jsp/homepage.jsp" />
        <add-attribute value="/WEB-INF/tiles/footer.jsp" />
    </put-list-attribute>
</definition>

<definition name="t.homepage" extends="t.base" preparer="com.blogspot.symfonyworld.lyricsbase.controller.TestViewPreparer">
    <put-attribute name="title" value="lyricsBase : home of lyrics" />
    <put-attribute name="view" value="homepage" cascade="true" />
    <put-list-attribute name="body">
        <add-attribute value="/WEB-INF/jsp/homepage.jsp" />
        <add-attribute value="/WEB-INF/tiles/footer.jsp" />
    </put-list-attribute>
</definition>
