BorderLayout test doesn't work

[alona.oz]

I tried to play a little with this library and copied the following
example from showcase examples.
But when I run it, it looks different and doesn’t seem to be as the
example. The buttons are not placed by regions, they placed as one
horizontal stack.

What I miss here?

public class Hello implements EntryPoint {

public void onModuleLoad() {


LayoutPanel layoutPanel = new LayoutPanel(new BorderLayout());
final Button b1 = new Button("NORTH");
final Button b2 = new Button("SOUTH");
final Button b3 = new Button("WEST");
final Button b4 = new Button("EAST");
final Button b5 = new Button("CENTER");

layoutPanel.add(b1, new
BorderLayoutData(BorderLayout.Region.NORTH,"10", "200"));

layoutPanel.add(b3, new
BorderLayoutData(BorderLayout.Region.WEST, "10", "200"));
layoutPanel.add(b4, new
BorderLayoutData(BorderLayout.Region.EAST, "10", "200"));
layoutPanel.add(b5, new
BorderLayoutData(BorderLayout.Region.CENTER, true));
layoutPanel.add(b2, new
BorderLayoutData(BorderLayout.Region.SOUTH, "10", "200"));

layoutPanel.setWidth("100%");
layoutPanel.setHeight("100%");

RootPanel.get().add(layoutPanel);
}


}

Hello,

You must layoutPanel.layout(); before
RootPanel.get().add(layoutPanel);

I've added this line, but still the same...
I suspect it's related to broswer version or type.
I used IE 8, now I tried to run it it Chrome and I received the
follwoing exception in GWT console:

00:00:15.393 [ERROR] Unable to load module entry point class

May it be related?

Your exception is about the drag and drop library but your code
doesn't need it to work.
Maybe should you modify your .gwt.xml file.

I just added the following lines to mine .gwt.xml file and the code is
OK :

<!-- Modules Mosaic -->
<inherits name='org.gwt.mosaic.Mosaic' />
<inherits name='org.gwt.mosaic.actions.Actions' />
<inherits name='org.gwt.mosaic.forms.Forms' />
