Layout Apache Tiles 2 from many templates

Question

I am building a web application using Spring 3 and Tiles 2.2. I applied the following layout definition:

<tiles-definitions>  
<definition name="default" template="/WEB-INF/layouts/default.jspx">  
<put-attribute name="header" value="main.header" />  
<put-attribute name="top_menu" value="/WEB-INF/views/top_menu.jspx" />  
<put-attribute name="left_column" value="main2.left_column" />  
<put-attribute name="main_column" value="main2.main_column" />  
<put-attribute name="footer" value="/WEB-INF/views/footer.jspx" />  
</definition> 

<definition name="main2.main_column" template="/WEB-INF/layouts/double_column/main_column.jspx">  
</definition>

<definition name="main2.left_column" template="/WEB-INF/layouts/left_column.jspx">  
        <put-attribute name="profile_menu" value="/WEB-INF/views/userprofile/userdetails.jspx" />  
        <put-attribute name="common_menu" value="/WEB-INF/views/menu.jspx" />  
      </definition>  
</tiles-definitions>

In WEB-INF / layouts / default.jspx

<div id="main_page" >   
    <tiles:insertAttribute name="left_column"/>    
    <tiles:insertAttribute name="main_column"/>   
        <div id="footer" >  
<tiles:insertAttribute name="footer" ignore="true"/>  
                </div>  
            </div>  

Now in / WEB -INF / layouts / double_column / main_column.jspx I have:

<tiles:insertAttribute name="body"/>  

The requested view.xml path is defined as follows:

<tiles-definitions>  
    <definition extends="default" name="secure/createAccount/*">  
        <put-attribute name="body" value="/WEB-INF/views/secure/createAccount/{1}.jspx"/>  
    </definition>  
</tiles-definitions>

and error:

org.apache.tiles.template.NoSuchAttributeException: Attribute 'body' not found.

    org.apache.tiles.template.InsertAttributeModel.resolveAttribute (InsertAttributeModel.java:187)
