How to use FXMLLoader.load() - JavaFX 2

I am building a JavaFX application using the JavaFX Scene Builder. The interface was created in the Scene Builder and a FXML file (main.fxml) was created.

To use the interface in my application I must load the FXML file using the FXMLLoader, but there is a problem because the load() method returns an Object, and to build a Scene I need an instance of Parent class.

Below is a piece of my MainClass. The compiler is giving an error because page is not of type Parent:

Object page = FXMLLoader.load(MainWindowController.class.getResource("main.fxml"));
Scene scene = new Scene(page);
primaryStage.setScene(scene);
primaryStage.show();

What do I do to make this compile and run correctly?

Here is the FXML file (main.fxml):

<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.paint.*?>

Due to a variety of entities eligible to be loaded through FXML you need to state the expected type yourself.

Parent page = FXMLLoader.<Parent>load(MainWindowController.class.getResource("main.fxml").toExternalForm());
