That's the beauty of that Swing tree model. It should work as the selection is held in the TreeState object. So if you set OptimizeItemRemoval to false, it triggers redrawing the child components everytime, but using the current tree state. So, just setting that flag - btw the new method name for this will be setReuseItems, which is consistent with the ListView method, though I just comitted that) - should suffice.
