Vernon, Have you read "Tiles Advanced Features" by Cedric Dumoulin? It is listed under the Struts userGuide section for Tiles, http://struts.apache.org/userGuide/dev_tiles.html with a direct URL of: http://www.lifl.fr/~dumoulin/tiles/tilesAdvancedFeatures.pdf
Read all subsections under section 4.1 as it will better explain (and with examples) what I was talking about. I am unsure if this is a requirement or just something I learned through trial and error, but when I extend a definition and add a new component, I make sure to add it to every parent tile (i.e. "this" extended "that" so I add the fields to "that", but "that" extended "another" so I added those same component names with some default value to "another.") back up the tree of definitions. If you do not define attributes in that strict a manner, you may fine, as other posters have discovered, that some tiles' JSP pieces/pages may not be able to see your attributes, especially if your "body" component is a JSP that needs access to the other tile components. I'm not explaining this well but the PDF is excellent in describing tiles concepts with numerous examples.
