I saw this question too, but I still can't make it work. I realized that when I calling a method it have red circle () like regular method that returns void (Netbeans IDE).
Here is aaaa method:
public void aaaa(ActionEvent event) {
System.out.println("aaaaaaaaaaaaaa");
}
Is this a normal for Netbeans IDE? Anyway, normal or not, my method is never called. Just to mention I don't have nested forms!
