How to get the text from multiple text fields? Net beans and Scene Builder

I have a problem with getting text from multiple text fields. I'm using Net Beans with Scene Builder as an UI-Extension. Every time I run the program, I get the following error:

Exception in thread "JavaFX Application Thread" java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

I have initialized my text fields' as follows: EmailController.java

@FXML private TextField txtTo;
@FXML private TextField txtSubject;
@FXML private TextField txtMessage;

And when I press 'send' I want to print the text I got from my text fields.

txtMessage being a multiline textfield.

EmailController.java

@FXML
private void handleSendAction(ActionEvent event) {
    System.out.println(txtTo.getText());
    System.out.println(txtSubject.getText());
    System.out.print(txtMessage.getText());
}

Any help would be much appreciated.

TextField and TextArea are two different controls. In the FXML file she declared that TextArea but in the controller annotated TextField.

For the code to go mad

@FXML private TextField txtMessage;

With

@FXML private TextArea txtMessage;
