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" />

In the controller, I use

@FXML

Here is the MainElementView.fxml :

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

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

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?

You need to append Controller to the fx:id to get the name of the field where the controller of the <fx:include> element is is injected. If you use the fx:id itself as field name, the object created for the root elment of the included fxml is injected.

I lost 4 hours because of that... Thanks for your help I didn't know the "controller" was important in the name.

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?

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);

    }

  }

}

You need to append Controller to the fx:id to get the name of the field where the controller of the <fx:include> element is is injected. If you use the fx:id itself as field name, the object created for the root elment of the included fxml is injected.
