Problem with Alignment

[GilbertGrape]

Hi,

I have a problem aligning a panel.
Here my code:

public class SmartGwtTests implements EntryPoint {

	
	/**
	 * This is the entry point method.
	 */
	public void onModuleLoad() {
		getPanel().draw();
	}
	
	private HLayout getPanel(){
		HLayout titlePanel = new HLayout();
		titlePanel.setWidth100();
		titlePanel.setHeight100();
		HLayout buttonPanel = new HLayout();
		buttonPanel.setWidth(100);
		buttonPanel.setHeight(30);
		titlePanel.setBorder("2px solid blue");
		buttonPanel.setBorder("2px solid red");
		buttonPanel.setAlign(Alignment.RIGHT);
		Button btn = new Button("Test");
		buttonPanel.addMember(btn);
		titlePanel.addMember(buttonPanel);		
		
		return titlePanel;
	}
}

As you can see, I try to align the buttonPanel on the right side, but it is shown on the left.
I'm already going crazy. It is such an easy functionality and I don't get it.
Could someone help?

Thanks
GG
