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

public class Application extends ERXApplication {

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.
