Button alignment problem

[Budfudder]

I have a simple window running but am unable to right-align the buttons. No matter what I do, they align to the left. Here's my code:

        // Create and format the window.
        final Window winSystem = new Window();
        winSystem.setWidth(300);
        winSystem.setHeight(200);
        winSystem.setShowMinimizeButton(false);
        winSystem.setIsModal(true);
        winSystem.setShowModalMask(true);
        winSystem.centerInPage();

        // Create the form to go on the window.
        final DynamicForm form = new DynamicForm();
        form.setHeight100();
        form.setWidth100();
        form.setPadding(5);
        form.setLayoutAlign(VerticalAlignment.BOTTOM);
        form.setDataSource(SystemListGridDataSource.getInstance());

        // Add the text items for the form.
        TextItem textName = new TextItem("Name");
        textName.setTitle("Name");
        textName.setSelectOnFocus(true);
        textName.setWrapTitle(false);
        textName.setLength(128);


        TextItem textComment = new TextItem("Comment");
        textComment.setTitle("Comment");
        textComment.setSelectOnFocus(true);
        textComment.setWrapTitle(false);
        textComment.setLength(128);

        // Add all the fields to the form.
        form.setFields(textName,
                       textComment);


        // Create a layout and add the form to it.
        VLayout vLayout = new VLayout();
        vLayout.setAlign(Alignment.RIGHT);
        vLayout.addMember(form);

        // Create the cancel button.
        Button buttonCancel = new Button("Cancel");
        buttonCancel.setLayoutAlign(Alignment.RIGHT);
        buttonCancel.addClickHandler(new ClickHandler()
        {
            public void onClick(ClickEvent event)
            {
                winSystem.destroy();
            }
        });

        // Create the OK button.
        Button buttonOK = new Button("OK");
        buttonOK.setLayoutAlign(Alignment.RIGHT);
        buttonOK.addClickHandler(new ClickHandler()
        {
            public void onClick(ClickEvent event)
            {
                if (form.validate())
                {
                    form.saveData();
                    winSystem.destroy();
                }
            }
        });

        // Create a layout to hold the buttons.
        HLayout buttonLayout = new HLayout();
        buttonLayout.setLayoutAlign(Alignment.RIGHT);
        buttonLayout.addMember(buttonOK);
        buttonLayout.addMember(buttonCancel);

        // Add the button layout to the layout and then add the layout to the
        // window.
        vLayout.addMember(buttonLayout);
        winSystem.addItem(vLayout);
        winSystem.show();

Any suggestions?

Use the Watch Tab in the Developer Console. The buttonLayout is as wide as the Window so it doesn't matter what it's layoutAlign setting is.

Any one of the following 3 approaches would fix it.
1. setAlign(RIGHT) on the buttonLayout so it's members align right
2. set buttonLayout's width smaller so layoutAlign can have an effect
3. add a LayoutSpacer before the buttons
