JavaFX custom controller factory

Question

I have been experimenting with the FXMLLoader and using the setControllerFactory method using a custom Callback implementation.

Answer 1

javafx does the following in FXMLLoader:

    try {
      if (controllerFactory == null) {
        setController(ReflectUtil.newInstance(type));
      } else {
        setController(controllerFactory.call(type));
      }
    } catch (InstantiationException exception) {
      throw new LoadException(exception);
    } catch (IllegalAccessException exception) {
      throw new LoadException(exception);
    }

so, yes, the oracle tutorial is incorrect.
