This is (IMHO) a classic issue with tiles. The Tiles meaning of
'inheritance' isn't quite the same as in Java or other OO concepts. Tiles
inherit values from their parents, and can override those values. However,
adding new values is not supported.
The only way [that I've found, anway] that you can support the
addition of new properties is to use the tiles importAttribute tag (see
http://jakarta.apache.org/struts/userGuide/struts-tiles.html#importAttribute
) in the main layout JSP, i.e. /layout/classicLayout.jsp, to pass the values
into a scope where they can be found by other tags such as <bean:write> and
use the values that way.
