Hi,

I'm testing GXT 3.0.0b and building a sample app.
When nesting ContentPanel inside a TabPanel, i'm facing the following problem : the first tab is always displaying correctly but the content of the following tabs is not correct (only a part of the button is visible or the whole content is missing).

Here is the screenshot gxt_problem.jpg

And the source code of the example :

Code:
public class Application implements EntryPoint {

    public void onModuleLoad() {


        BorderLayoutContainer mainContainer = new BorderLayoutContainer();


        TabPanel mainTabPanel = new TabPanel();


        BorderLayoutData centerData = new BorderLayoutData();
        centerData.setMargins(new Margins(5));


        VerticalLayoutContainer mainContent = new VerticalLayoutContainer();
        mainContent.add(mainTabPanel, new VerticalLayoutData(1, 1));


        mainContainer.setCenterWidget(mainContent, centerData);


        mainTabPanel.setBodyBorder(false);
        mainTabPanel.setResizeTabs(true);
        mainTabPanel.setTabWidth(Integer.MAX_VALUE);


        VerticalLayoutContainer contentPanel1Container = new VerticalLayoutContainer();
        ContentPanel contentPanel1 = new ContentPanel();
        contentPanel1.setPixelSize(500, 250);
        contentPanel1.addButton(new TextButton("Submit 1"));
        contentPanel1Container.add(contentPanel1);


        VerticalLayoutContainer contentPanel2Container = new VerticalLayoutContainer();
        ContentPanel contentPanel2 = new ContentPanel();
        contentPanel2.setPixelSize(500, 250);
        contentPanel2.addButton(new TextButton("Submit 2"));
        contentPanel2Container.add(contentPanel2);


        mainTabPanel.add(contentPanel1Container, "Tab 1");
        mainTabPanel.add(contentPanel2Container, "Tab 2");


        Viewport viewport = new Viewport();
        viewport.add(mainContainer);


        RootPanel.get().add(viewport);
    }
}
Is it possible to use a content panel inside a tab panel? Should I use another container?
