hello,

i am trying to implement a portal from the example and i found that the columns shift if it does not contain any portlets in it...

i can't figure what is wrong..please help..

Code:
var PortalViewport = new Ext.Viewport({
    id: 'MyAppsPortalViewport',
    layout: 'border',
    items: [
        {
            id: 'HeaderPanel',
            region: 'north',
            height: 50,
            padding: 13,
            border: false,
            cls: 'HeaderPanel',
            items: [ 
                Ext.MyApps.getMainMenu()
            ]
        },
        {
            xtype: 'portal',
            region: 'center',
            autoScroll: true,
            items: [
                {
                    id: 'PortalPanelLeftColumn',
                    columnWidth: 0.25,
                    items:  [
                        {
                            title: 'Panel 2',
                            html: 'Test',
                            title: 'Another Panel 2'
                        }
                    ]
                },
                {
                    id: 'PortalPanelCenterColumn',
                    columnWidth: 0.50,
                    items:  [
                        {
                            title: 'Panel 2',
                            html: 'Test',
                            title: 'Another Panel 2'
                        }
                    ]
                },
                {
                    id: 'PortalPanelRightColumn',
                    columnWidth: 0.25,
                    items:  [
                        {
                            title: 'Panel 2',
                            html: 'Test',
                            title: 'Another Panel 2'
                        }
                    ]
                }
            ]
        },
        {
            id: 'FooterPanel',
            region: 'south',
            height: 30,
            border: false,
            cls: 'FooterPanel'
        }
    ]
});
