Simple BorderLayout Example not working

[anasmughal]

Below a simple BorderLayout example that is exhibiting a problem. If I collapse the South panel, I can't bring it back again. Moreover, if I collapse the north panel, the South panel disappears. Is there something wrong in my code or the GXT library has a bug?

Thank you for your help.

public void onModuleLoad() {

        LayoutContainer lcontainer = new LayoutContainer();
        lcontainer.setLayout(new BorderLayout());   
        
        ContentPanel north = new ContentPanel();
        ContentPanel west = new ContentPanel();              
        ContentPanel center = new ContentPanel();
        ContentPanel east = new ContentPanel();
        ContentPanel south = new ContentPanel();
        
        north.setHeading("North");
        west.setHeading("West");
        center.setHeading("Center");
        east.setHeading("East");
        south.setHeading("South");
        
        BorderLayoutData northData = new BorderLayoutData(LayoutRegion.NORTH, 100);  
        northData.setCollapsible(true);  
        northData.setFloatable(true);  
        northData.setSplit(true);  
        northData.setMargins(new Margins(5, 5, 0, 5));  
        
        BorderLayoutData westData = new BorderLayoutData(LayoutRegion.WEST, 200);  
        westData.setSplit(true);  
        westData.setCollapsible(true);  
        westData.setMargins(new Margins(5));  
        
        BorderLayoutData centerData = new BorderLayoutData(LayoutRegion.CENTER);  
        centerData.setMargins(new Margins(5, 0, 5, 0));  
        
        BorderLayoutData eastData = new BorderLayoutData(LayoutRegion.EAST, 200);  
        eastData.setSplit(true);  
        eastData.setCollapsible(true);  
        eastData.setMargins(new Margins(5));  
        
        BorderLayoutData southData = new BorderLayoutData(LayoutRegion.SOUTH, 100);  
        southData.setSplit(true);  
        southData.setCollapsible(true);  
        southData.setFloatable(true);  
        southData.setMargins(new Margins(0, 5, 5, 5));  
        
        lcontainer.add(north, northData);  
        lcontainer.add(west, westData);  
        lcontainer.add(center, centerData);  
        lcontainer.add(east, eastData);  
        lcontainer.add(south, southData);
        
        RootPanel.get().add(lcontainer);
}

yes. you didn't size the layoutcontainer - setSize(800,600) would fix this

...or, add to viewport with fitlayout and it will resize with browser

That solved the problem. Now the south panel does not disappear.

Thank you very much.
