I have a problem with a javaFX project.

I have a fxml including another one :

<?import javafx.scene.control.ListView?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.BorderPane?>
<?import javafx.scene.layout.VBox?>

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="1200.0" prefWidth="1600.0" stylesheets="@../css/mainWindow.css" xmlns="http://javafx.com/javafx/8.0.141" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.spaceopera.client.ihm.mainwindow.MainWindowController">
 <children>
 <BorderPane fx:id="mainPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="1200.0" prefWidth="1600.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0">
 <top>
 <ListView fx:id="gameMenu" onMouseClicked="#handleGameMenuClick" orientation="HORIZONTAL" prefHeight="100.0" prefWidth="1600.0" style="-fx-background-color: orange;" BorderPane.alignment="CENTER" />
 </top>
 <left>
 <ListView fx:id="planetMenu" onMouseClicked="#handlePlanetMenuClick" minHeight="1100.0" minWidth="200.0" maxHeight="1100.0" maxWidth="200.0" prefHeight="1100.0" prefWidth="200.0" style="-fx-background-color: blue;" />
 </left>
 <right>
 <ListView fx:id="empireMenu" onMouseClicked="#handleEmpireMenuClick" minHeight="1100.0" minWidth="200.0" maxHeight="1100.0" maxWidth="200.0" prefHeight="1100.0" prefWidth="200.0" style="-fx-background-color: red;" BorderPane.alignment="CENTER" />
 </right>
 <center>
 <fx:include fx:id="mainElement" source="MainElementView.fxml"/>
 </center>
 </BorderPane>
 </children>
</AnchorPane>

In the controller, I use

@FXML
private MainElementViewController mainElement;
To access to the included element

Here is the MainElementView.fxml :

<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.layout.VBox?>


<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="100.0" prefWidth="1200.0" stylesheets="@../css/specificElement.css" xmlns="http://javafx.com/javafx/8.0.141" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.spaceopera.client.ihm.mainwindow.mainelement.MainElementViewController">
 <children>

 </children>
</AnchorPane>

The ode of MainElementViewController.java :

package com.spaceopera.client.ihm.mainwindow.mainelement;

import com.spaceopera.client.ihm.mainwindow.mainelement.specificelement.SpecificElementViewController;
import java.net.URL;
import java.util.List;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.layout.AnchorPane;

/**
 *
 * @author olivier
 */
public class MainElementViewController extends AnchorPane implements Initializable 

 @FXML
 SpecificElementViewController specificElement;

 private List<String> elementTypesList;

 public MainElementViewController() 

 

 @Override
 public void initialize(URL location, ResourceBundle resources) 
 

 public List<String> getElementTypesList() 
 return elementTypesList;
 

 public void setElementTypesList(List<String> elementTypesList) 
 System.out.println("plop");
 this.elementTypesList = elementTypesList;
 specificElement.setElementTypes(elementTypesList);
 

And here is the SpecificElementView.xml :

<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.control.ListView?>

<AnchorPane id="AnchorPane" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="100.0" prefWidth="1200.0" stylesheets="@../css/specificElement.css" xmlns="http://javafx.com/javafx/8.0.141" xmlns:fx="http://javafx.com/fxml/1" fx:controller="com.spaceopera.client.ihm.mainwindow.mainelement.specificelement.SpecificElementViewController">
 <children>
 <ListView fx:id="elementTypes" onMouseClicked="#handleSpecificElementClick" orientation="HORIZONTAL" prefHeight="100.0" prefWidth="1200.0" style="-fx-background-color: purple;" />
 </children>
</AnchorPane>

And the java :

package com.spaceopera.client.ihm.mainwindow.mainelement.specificelement;

import java.net.URL;
import java.util.List;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.ListView;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.AnchorPane;

/**
 *
 * @author olivier
 */
public class SpecificElementViewController extends AnchorPane implements Initializable 

 private List<String> elementTypesList;

 @FXML
 private ListView elementTypes;

 public SpecificElementViewController() 
 

 @Override
 public void initialize(URL location, ResourceBundle resources) 
 

 @FXML
 public void handleSpecificElementClick(MouseEvent arg) throws Exception 
 throw new Exception("Not implemented yet!!!");
 

 public List<String> getElementTypes() 
 return elementTypesList;
 

 public void setElementTypes(List<String> elementTypesList) 
 this.elementTypes = elementTypes;
 elementTypes.getItems().clear();
 for (String s : elementTypesList) 
 System.out.println("type : " + s);
 elementTypes.getItems().add(s);
 
 

When i run it, I have an exception :

avafx.fxml.LoadException:

If I remove the include in MainElementView.fxml, I have the same exception on the include in the MainWindow.fxml (with problem to set MainElement to anchorpane instead of specificElement).

Can you help me to fix this pls?
