Hi. I have the border layout and my center region in the viewport is defined like this:
Code:
{
                     region: 'center',
                     id: 'centerRegion',
                    contentEl: 'center1'
}
I can get this element by
Code:
Ext.getCmp('centerRegion')
The question is how can i dynamically replace content in the center region with the grid for example.
