I'm trying to redo an existing panel that I made before GWT 2.0 was released. The panel has a few text fields and a scrollable panel below in a VerticalPanel.

What I'd like to do is to make the scrollable panel with UIBinder and then add that to a VerticalPanel Below is an example I created to illustrate this:

 public class ScrollTablePanel extends ResizeComposite{

     interface Binder extends UiBinder<Widget, ScrollTablePanel > { }
     private static Binder uiBinder = GWT.create(Binder.class);

     @UiField FlexTable table1;
     @UiField FlexTable table2;

     public Test2() {

      initWidget(uiBinder.createAndBindUi(this));



      table1.setText(0, 0, "testing 1");
      table1.setText(0, 1, "testing 2");
      table1.setText(0, 2, "testing 3");

      table2.setText(0, 0, "testing 1");
      table2.setText(0, 1, "testing 2");
      table2.setText(0, 2, "testing 3");
      table2.setText(1, 0, "testing 4");
      table2.setText(1, 1, "testing 5");
      table2.setText(1, 2, "testing 6");
     }
    }

then the xml:

<ui:UiBinder 
   xmlns:ui='urn:ui:com.google.gwt.uibinder' 
   xmlns:g='urn:import:com.google.gwt.user.client.ui'       
   xmlns:mail='urn:import:com.test.scrollpaneltest'>
       <g:DockLayoutPanel unit='EM'>
      <g:north size="2">
       <g:FlexTable ui:field="table1"></g:FlexTable>
      </g:north>
      <g:center>
       <g:ScrollPanel>
         <g:FlexTable ui:field="table2"></g:FlexTable>
       </g:ScrollPanel>
      </g:center>
    </g:DockLayoutPanel>
</ui:UiBinder>

Then do something like this in the EntryPoint:

 public void onModuleLoad() {

     VerticalPanel vp = new VerticalPanel();
     vp.add(new ScrollTablePanel());
     vp.add(new Label("dummy label text"));
     vp.setWidth("100%");

     RootLayoutPanel.get().add(vp);
    }

But when I add the ScrollTablePanel to the VerticalPanel, only the first FlexTable (test1) is visible on the page, not the whole ScrollTablePanel.

Is there a way to make this work where it is possible to mix declarative and programmatic layout in GWT 2.0?
