Test case

        BorderLayoutContainer borderLayoutContainer = new BorderLayoutContainer();

        BorderLayoutData northData = new BorderLayoutData(100);
        northData.setMargins(new Margins());

        BorderLayoutData westData = new BorderLayoutData(180);
        westData.setMargins(new Margins(0, 3, 0, 0));
        westData.setCollapsible(true);
        westData.setSplit(true);

        MarginData centerData = new MarginData();

        BorderLayoutData eastData = new BorderLayoutData(250);
        eastData.setMargins(new Margins(0, 0, 0, 3));
        eastData.setCollapsible(true);
        eastData.setSplit(true);

        BorderLayoutData southData = new BorderLayoutData(180);
        southData.setMargins(new Margins(3, 0, 0, 0));
        southData.setCollapsible(true);
        eastData.setSplit(true);

        ContentPanel west = new ContentPanel();
        ContentPanel north = new ContentPanel();

        borderLayoutContainer.setWestWidget(west, westData);
        borderLayoutContainer.setNorthWidget(north, northData);

        Viewport viewport = new Viewport();
        viewport.setWidget(borderLayoutContainer);

        RootLayoutPanel.get().add(viewport);

        ContentPanel east = new ContentPanel();
        ContentPanel south = new ContentPanel();
        ContentPanel center = new ContentPanel();

        borderLayoutContainer.setEastWidget(east, eastData);
        borderLayoutContainer.setSouthWidget(south, southData);
        borderLayoutContainer.setCenterWidget(center, centerData);
    }

}

Helpful Information Screenshot or video Live test Debugging already done

• BorderLayoutContainer.onInsert line 984 c.isRendered() will return true when the BorderLayoutContainer is rendered

Thanks for the report and the test case. I'm able to reproduce this issue. I've filed a bug against the team and will update this thread with any changes we make.

If you add items to a container after that container has been rendered, you will need a call to that container's doLayout or forceLayout in order to have it render correctly. This is not a bug in the framework.
