Hello,
Actually, definitions are used to associate a layout (page="aLayout.jsp) and
some attributes. Attributes are parameters provided to layout. The Layout can use
its provided attributes as it wants.
What you are trying to do is to use a definition to define a List. Of course
this doesn't work.
A solution is to create a small Tiles that you associate to your definition
blueTheme. This Tiles do the <style type ...> tag using the provided list.
Hope this help,
Cedric
