reference problem in drag and drop

hi

i add some ButtonComponent on a jpanel.
ButtonComponent extend jbutto and have an object who have some property.

 private JButton createSimpleButton(CommandBeans commandBeans) {
        ButtonComponent button = new ButtonComponent(commandBeans);
        button.setTransferHandler(new MyTransferHandler());

        button.addMouseListener(new MouseAdapter() {
            @Override
            public void mousePressed(MouseEvent e) {
                JComponent lab = (JComponent) e.getSource();
                TransferHandler handle = lab.getTransferHandler();
                handle.exportAsDrag(lab, e, TransferHandler.COPY);
            }
        });
        return button;
    }

in the getCommand function of my ButtonComponent i do

 return (CommandBeans) BeanUtils.cloneBean(command);

it's like i have a reference problem because when i drag a component, change property of object, i drag another one... object property have same values then the first one.

any idea?

thanks

instead of used this code

String mimeType = DataFlavor.javaJVMLocalObjectMimeType + ";class=" + CommandBeans.class.getName();
DataFlavor dataFlavor = new DataFlavor(mimeType, "command");

in my Transferable, TransferHandler class

i used

DataFlavor dataFlavor = new DataFlavor(CommandBeans.class,CommandBeans.class.getSimpleName());

that seem to have fixed the reference problem.
