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.
A fatal exception occurred: No key operator available to compute aggregate @unique.divisions.title
java.lang.IllegalArgumentException: No key operator available to compute aggregate @unique.divisions.title

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