| ERXApplication itself extends ERXAjaxApplication ... You're not getting @unique because ERXAjaxApplication doesn't do any of the other Wonder extensions other than just enough to support Ajax. I'd need more info about the backtrack errors to be able to help you there. You're getting backtrack errors doing what and using which components?

This is what I had - but I got occasional back track limit exceed errors:
public class Application extends ERXApplication {
public static void main(String[] argv) {
ERXApplication.main(argv, Application.class);
}
So now Application class extends from ERXAjaxApplication
public class Application extends ERXAjaxApplication {
public static void main(String[] argv) {
ERXAjaxApplication.main(argv, Application.class);
}
But I get these errors. It is almost as if it does not find the ERXExtensions framework and the ERXArrayUtilities class.

If I switch back to extending from ERXApplication, it finds it (@unique) and loads fine.
But then I get occasional backtracking errors.
