Hi,
I have a simple setup where I am creating a few rectangles and just want to be able to scroll through them.
Cant seem to get this working, any help will be most appreciated!

import javafx.scene.control.ScrollBar;
import javafx.scene.Group;
import javafx.scene.CustomNode;
import javafx.scene.Node;
import javafx.scene.paint.Color;
import javafx.scene.shape.Rectangle;
var Schedule:HourlySchedule[];
package class HourlySchedule extends CustomNode {
public var yPos: Number;
     public override function create(): Node {
         return Group {
             translateY: yPos - 5
             content: [
                 Rectangle {
                     //x: 10, y: 10
                     width: 425, height: 28
                     fill: Color.WHITE
                     stroke: Color.BLACK
public function run()
    for (i in [0..23]){
        insert HourlySchedule{yPos: i * 32}into Schedule
    var scroll = ScrollBar {
        translateX: 450
        translateY: 25
        height: 350
        scaleX: 0.5
        blockIncrement: 16
        clickToPosition: false
        min: 0
        max:12
        vertical: true
    var rect_height: Integer = 35;
    var ScheduleList: Group = Group {
       translateY: bind 0 - scroll.value * rect_height
         content: [ Schedule ]
Stage {
    title: "Scrolling"
    x: 100
    y:100
    width: 1050
    height: 468
    scene: Scene {
        content:[ScheduleList,scroll]
}

wow, that's weird.
This is the error I get on executing that code:
standard-run:
