I added a tree to the center region of a border layout. I set the autoscroll property of the center region to true which allows me to scroll the tree but the tree columns scroll away and are not visible. I noticed that the grid component supports the "frozen" component which freezes the columns in a grid. But, the tree component does not support the same. When I try adding a frozen component to the tree, I see an unsupported child exception.
I would like the "Name" and "Type" columns of my tree to freeze as I scroll. Please see my code attached.
