Using Grid in PopupView problem

Hi,

I have a problem, using a Grid in a PopupView. If the PopupView openes, there seems to be a refresh problem. The same is working with a table.

final Table table = new Table();
        table.setHeight("500px");
        table.setWidth("500px");
        table.addContainerProperty("A", String.class, null);
        table.addContainerProperty("B", String.class, null);
        table.addContainerProperty("C", String.class, null);
        
        final Grid grid = new Grid();
        grid.setHeight("500px");
        grid.setWidth("500px");
        grid.addColumn("A", String.class);
        grid.addColumn("B", String.class);
        grid.addColumn("C", String.class);
        setCompositionRoot(new VerticalLayout( new PopupView("table", table), new PopupView("grid", grid) ));

Is there anybody with the same problem?

Thanks Dennis
