Problem with image url

Question

Hello,
today I have a problem with image url. I wanted Image to change when mouse dragged over it. But nothing happened. Any ideas?
def maxIco: ImageView = ImageView{
image: Image{
url: "{__DIR__}ikony/max.png"
onMouseDragged: function(event: MouseEvent){
maxIco.image = Image{
url: "{__DIR__}ikony/max2.png"
}

This is working for me:
src/main/Main.fx
src/main/icon/image1.bmp
src/main/icon/image2.bmp
//Main.fx
package main;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseEvent;
var changed = false;
def imgView: ImageView = ImageView {
    image: Image {
        url: "{__DIR__}icon/image1.bmp"
    onMouseDragged: function (e: MouseEvent): Void {
        if (not changed) {
            imgView.image = Image {
                url: "{__DIR__}icon/image2.bmp"
            changed = true;
            println(imgView.image.url);
    onMouseReleased: function (e: MouseEvent): Void {
        imgView.image = Image {
            url: "{__DIR__}icon/image1.bmp"
        changed = false;
        println(imgView.image.url);
Stage {
    title: "ImageTest"
    scene: Scene {
        width: 700
        height: 600
        content: [
            imgView
}I've changed few things to switch image only one time on mouseDragged event.
It print the image URL.
