Attribute from a tile are only visible inside this tile (like parameters of a
methods). If you set some attributes in the controller, these attribute are
visible to the tile attached to your controller (here your layout.jsp), not to
tiles inserted by controller. If you want them to be visible, you need to pass
them effectively when you insert (sub-)tiles :
<tiles:insert attribute="add" >
<tiles:put name="aName" beanName="aName" beanScope="tile" />
<tiles:insert/>
Unfortunately, this imply to modify your layout.
Another solution is to put your attribute values in the request scope rather
than in the tile context scope. Like this, their will be available in all
inserted tiles.

In the controller you can specify a value for the attribute "preview". In your
case, specify the name of a definition or the url of a page to use.
Code will look something like :
// Select preview url according to client choice
String url = .....
// Set / override preview value url :
if(url != null )
tileContext.setAttribute( "preview", url );
