That can't be the markup that generated that error because there is no tag in
it with a wicket:id="label" which the error message is complaining about.
But you also do not add a tag for exampleTitle which you add here
add(new Label("exampleTitle", exampleTitle));
Basically, every wicket:id in your html files must have a component in your
java file and visa versa
