Below is a reply sent to this mailing list about something very similar to
what you are looking for.
Hope it helps,

Hi Robert..
I guess you could achieve the same using the controllerClass attribute and
building your class.. For instance, I have this definition in the
tiles-defs.xml file:
---
<definition name=".layout"
path="/common/layout.jsp"
controllerClass='com.dars.XTileAction'>
<put name="title" value="Encabezado primario"/>
<put name="leftside" value="/common/leftside.jsp"/>
<put name="rightside" value="/common/rightside.jsp"/>
<put name="header" value="/common/header.jsp"/>
<put name="footer" value="/common/footer.jsp"/>
<put name="body" value="/common/body.jsp"/>
</definition>
---
And I have this controllerClass
---
package com.dars;
import org.apache.struts.tiles.actions.TilesAction;
import org.apache.struts.tiles.ComponentContext;
import org.apache.struts.tiles.Controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import java.io.IOException;
public class XTileAction extends TilesAction implements Controller{
public void perform(ComponentContext tilesctx,
HttpServletRequest request,
HttpServletResponse response,
ServletContext servctx)
throws ServletException, IOException{
/* GetAttributes */
String titulo= (String)tilesctx.getAttribute("title");
String derecha= (String)tilesctx.getAttribute("rightside");
/* GetAttributes */
System.out.println(" Titulo: "+titulo);
System.out.println(" Derecha: "+derecha);
/* SetAttributes */
tilesctx.putAttribute("title", "Titulo nuevo de esta vaina..");
tilesctx.putAttribute("rightside", "/common/footer.jsp");
/* SetAttributes */
}
}

You can change the values of those attributes at runtime. I prefer to do
it using this method.
Atte.
