What doesn't work in your example is that at a time you insert page
/middle.jsp without passing it any attribute. This page use an attribute in its
<insert> tag. You have two solution to pass the attribute :
* while you do the <insert> :
middle.jsp
<%@ taglib uri="/WEB-INF/tiles.tld" prefix="tiles" %>
<tiles:insert attribute="anotherBody">
<tiles:put beanName="anotherAttribute" beanScope="tile"/>
</tiles:insert>
* By defining a definition declaring the attribute, and then use the
definition name rather than the page url.
Remember that Tiles attribute values passed to a tile are only visible inside
this tile, not from its parent, neither from sub-tiles.
Doesn't the following solution met your needs ? :
<definition name="simpleLayout" path="/simpleLayout.jsp">
<put name="title" value="aBody"/>
<put name="header" value="aHeader"/>
<put name="footer" value="aFooter"/>
<put name="menu" value="amenu"/>
</definition>
<definition name="complexLayout" path="/complexLayout.jsp"
extends="simpleLayout">
<put name="header" value="complexHeader"/>
<put name="secondHeader" value="anotherHeader"/>
</definition>
<definition name="aSimplePage" extends="simpleLayout">
<put name="body" value="aPageBody"/>
</definition>
<definition name="aComplexPage" extends="complexLayout">
<put name="body" value="aPageBody2"/>
</definition>
