Disabled button does not look disabled

Question

In a simple FX app I created a button and set the disable property to true, for exampledeleteButton.disable = true The problem is that when I run the app the button does not look disabled. The only way I can tell if the button is enabled or disabled is by mousing over it: if I mouse over a disabled button nothing happens, if I mouse over an enabled button it flashes blue.
Is this a bug either FX or Nimbus, or am I doing something wrong?
Cheers, Eric

I've found the same problem and a "bugy way"
if in a Custom node:
var bts: Button[];
function setControl(b: Boolean) {
        for (bt in bts) {
            bt.disable = not b;
postinit {
        Timeline {
            keyFrames: KeyFrame {
                time: .2s
                action: function(): Void {setControl(false)}
        }.playFromStart();
public override function create(): Node {
        insert Button {
            //disable: bind not control
            text: "View"
            action: function(): Void {
                onView(boxNumber);
        } into bts;
        insert Button {
            //disable: bind not control
            text: "Print"
            action: function(): Void {
                onPrint(boxNumber);
        } into bts;
                        VBox {
                            layoutInfo: LayoutInfo {
                                width: 80
                            spacing: 5
                            content: [
                                bts
...Afterall it put an shinny effect on your screen, thank's javafx.control API ;-)
