Graphic object circle disappears during dragging table columns
TableView
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)


Hello!
I am using 64-bit Linux.
I have tested it on windows too. Result is same.
/usr/java/latest/bin/java -version
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)
I wrote a test project with TableView.
TableView has String elements in columns and circle element in one column.
Code:

    @FXML
    private static TableView table;
....
        TableColumn circleCol = new TableColumn("Circle");
....
        circleCol.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Person, MyCircle>, ObservableValue<MyCircle>>() {
            @Override
            public ObservableValue<MyCircle> call(TableColumn.CellDataFeatures<Person, MyCircle> p) {
                // p.getValue() returns the Person instance for a particular TableView row
                return p.getValue().getImg();
            }
        });
....


    public class MyCircle extends Circle{
        private int order;
        public MyCircle(double d,int order) {
            super(d);
            this.order=order;
        }

        public MyCircle(double d, Paint paint,int order) {
            super(d,paint);
            this.order=order;
        }

        public MyCircle() {
            super();
            this.order=order;
        }

        public MyCircle(double d, double d1, double d2,int order) {
            super(d,d1,d2);
            this.order=order;
        }

        public MyCircle(double d, double d1, double d2, Paint paint,int order) {
            super(d,d1,d2,paint);
            this.order=order;
        }
        
        @Override
        public String toString(){
            return order+"";
        }
    }


....
        table.getColumns().setAll(firstNameCol, lastNameCol, circleCol, numberCol, circleColStr);
       
....

When I am changing column orders by dragging columns the color circles disappears.
I think that this is a bug!
