我在javafx中使用装饰时出现问题

Question

这是我的装饰课

SELECT Date, Amount, SUM(Amount) OVER (ORDER BY Date) AS CumulativeTotal
FROM Table

这是我的抽象装饰类

public class decorateButton extends  addressDecorator {
    //public addressbookInterface address;
    public decorateButton(addressbookInterface AddressBookPane) {
        super(AddressBookPane);
        CommandButton add=new AddButton((AddressBookPane) super.address,((AddressBookPane)super.address).getRaf());
        CommandButton redo=new CommandButton((AddressBookPane)super.address,((AddressBookPane)super.address).getRaf());
        CommandButton undo=new CommandButton((AddressBookPane)super.address,((AddressBookPane)super.address).getRaf());
        redo.setOnAction(((AddressBookPane)address).ae);
        undo.setOnAction(((AddressBookPane)address).ae);
        add.setOnAction(((AddressBookPane)address).ae);
        ( ((AddressBookPane)(super.address)).getJpButton()).getChildren().addAll(add,redo, undo);

    }

    @Override
    public addressbookInterface getAddressBookPane() {
        return super.getAddressBookPane(); 

    }
}

我装饰了新的通讯簿，所以我需要添加3个按钮，但是我的类decoratButtons实际上是gridpane，所以我得到了gridpane内部的gridpane。
我的AddressBookPane是扩展网格窗格，我装饰了它

我的问题gridpane内部gridpane
