Sorry I dont know how to phrase this question any better.
Currently, I am specifying the spring mvc "form" taglib annotation (and a few others) in my main layout.
I would expect specifying these annotations in this location would eliminate the need to duplicate the same annotations in the other page fragments that comprise this tile definition.
But, it "appears", that my "body" fragment appears to work properly only if I re-specify the annotations there, as well.
e.g.,
<%@taglib uri="http://www.springframework.org/tags/form" prefix="form"%>

<definition name="masterpage" template="/WEB-INF/views/masterlayout.jsp">
<put-attribute name="title" value="" type="string"/>
<put-attribute name="header" value="" />
<put-attribute name="leftside" value="" />
<put-attribute name="rightside" value="" />
<put-attribute name="footer" value="" />
</definition>
<definition name="mypage" extends="masterpage">
<put-attribute name="title" value="My Page Title" type="string"/>
<put-attribute name="header" value="/WEB-INF/views/header.jsp" />
<put-attribute name="leftside" value="/WEB-INF/views/leftside.jsp" />
<put-attribute name="rightside" value="/WEB-INF/views/rightside.jsp"/>
<put-attribute name="footer" value="/WEB-INF/views/footer.jsp" />
</definition>

Because each JSP is independant from the others. Tiles uses dynamic includes behind the scenes.
And the whole point of a templating engine like Tiles is to be able to use the same components inside multiple layouts, and multiple components inside the same layout. Having a component's code depend on the layout it's included in is not a good idea.
