Why won't a JavaFx project run when an FXML file is replaced
Question
I've got a JavaFx project that I built using Netbeans and JavaFx Scene Builder.
There are 3 files: the Main Class file, the FXML file and the controller.
Now, the problem is that I'm trying to copy and paste an earlier GUI JXML file from a previous project, but when I do so, the project won't run. Changing the URL to the controller doesn't help.
Everything works perfectly until I do the copy-paste.
The files are:
Sample.FXML -> The orriginal GUI
SampleController.java -> The Controller class
Home.FXML -> The FXML file whose structure is to be copied to orriginal Sample.FXML
Here are the files:
Sample.FXML (before the copy)
<?xml version="1.0" encoding="UTF-8"?>
<?import java.lang.*?>
<?import java.util.*?>
<?import javafx.scene.*?>

<children>
<Button layoutX="126" layoutY="90" text="Click Me!" onAction="#handleButtonAction" fx:id="button" />
<Label layoutX="126" layoutY="120" minHeight="16" minWidth="69" fx:id="label" />
</children>
</AnchorPane>
SampleController.java
import java.net.URL;

@FXML

System.out.println("You clicked me!");
label.setText("Hello World!");
}
@Override

// TODO

}

A method called from the FXML file must be included somewhere in the controller class.
In this case the handleButtonActionShowHome() method had not been included in the SampleController class.
