Nesting Apache Tiles Template
提问by samsina
So I found this: http://tiles.apache.org/framework/tutorial/advanced/nesting-extending.html
所以我发现了这个：http: //tiles.apache.org/framework/tutorial/advanced/nesting-extending.html
Here is the example:
这是示例：
<definition name="myapp.homepage" template="/layouts/classic.jsp">
<put-attribute name="title" value="Tiles tutorial homepage" />
<put-attribute name="header" value="/tiles/banner.jsp" />
<put-attribute name="menu" value="/tiles/common_menu.jsp" />
<put-attribute name="body">
<definition template="/layouts/three_rows.jsp">
<put-attribute name="one" value="/tiles/headlines.jsp" />
<put-attribute name="two" value="/tiles/topics.jsp" />
<put-attribute name="one" value="/tiles/comments.jsp" />
</definition>
</put-attribute>
<put-attribute name="footer" value="/tiles/credits.jsp" />
</definition>
So I defined this:
所以我定义了这个：
<definition name="mgmt.base.layout" extends="base.layout">
<put-attribute name="body">
<definition template="/WEB-INF/mgmt/config/mgmtBody.jsp"/>
<put-attribute name="adminLeft" value="/WEB-INF/mgmt/config/left.jsp"/>
<put-attribute name="adminRight" value="/tiles/blank.html"/>
</definition>
</put-attribute>
</definition>
But the funny part is that, even their own documentation is wrong:
但有趣的是，即使他们自己的文档也是错误的：
2009-05-12 11:20:56,088 [main] ERROR - org.apache.commons.digester.Digester.error(Digester.java:1635): Parse Error at line 17 column 68: Attribute "name" is required and must be specified for element type "definition". org.xml.sax.SAXParseException: Attribute "name" is required and must be specified for element type "definition".
2009-05-12 11:20:56,088 [main] 错误 - org.apache.commons.digester.Digester.error(Digester.java:1635)：第 17 行第 68 列解析错误：属性“名称”是必需的，并且必须为元素类型“定义”指定。org.xml.sax.SAXParseException：属性“名称”是必需的，并且必须为元素类型“定义”指定。
Even though I define a name for it, it still gives the following error:
即使我为它定义了一个名称，它仍然会出现以下错误：
2009-05-12 11:35:31,818 [main] ERROR - org.apache.commons.digester.Digester.error(Digester.java:1635): Parse Error at line 21 column 19: The content of element type "put-attribute" must match "null". org.xml.sax.SAXParseException: The content of element type "put-attribute" must match "null".
2009-05-12 11:35:31,818 [main] 错误 - org.apache.commons.digester.Digester.error(Digester.java:1635)：第 21 行第 19 列的解析错误：元素类型的内容“put-属性”必须匹配“null”。org.xml.sax.SAXParseException：元素类型“put-attribute”的内容必须匹配“null”。
What is this mean?!!!!
这是什么意思？！！！！

The schema you use requires that put-attribute is a leaf node, i.e. can't contain child elements - so you can't do that. Find out if a newer version of the schema (must be in Tiles docs or examples) allows for nested tiles templates.
您使用的架构要求 put-attribute 是叶节点，即不能包含子元素 - 所以您不能这样做。了解较新版本的架构（必须在 Tiles 文档或示例中）是否允许嵌套的 Tiles 模板。

So basically I am using a older version of tiles and using new version schema: Here is the syntax for older nested schema: http://tiles.apache.org/2.0/framework/tutorial/advanced/nesting-extending.html
所以基本上我使用的是旧版本的瓷砖并使用新版本的架构：这是旧嵌套架构的语法：http: //tiles.apache.org/2.0/framework/tutorial/advanced/nesting-extending.html
