I haven't overridden anything in Application as far as I recall.

I'm not sure what the above code will do.  Are you recommending I add
this to Application?

My application code reads as below.

public class Application extends WOApplication {

     public static void main(String argv[]) {
         WOApplication.main(argv, Application.class);
     }

     public Application() {
         super();
         System.out.println("Welcome to " + this.name() + "!");
         System.out.println(" SMTPHost = " + this.SMTPHost());

         /* ** Put your application initialization code here ** */
         setAllowsConcurrentRequestHandling(true);
     }

     public WOResponse handleSessionRestorationErrorInContext(WOContext
context){
         Main nextPage = (Main)pageWithName("Main",context);
//        nextPage.doOrShowSomethingBecauseSessionTimedOut();
         //display message to user, etc...
         WOResponse response = nextPage.generateResponse();
         if(response == null){
             response =
super.handleSessionRestorationErrorInContext(context);
         }
         return response;
//        return nextPage;
     }

}
