Thanks for testing. At this point, I consider this a bug, that the tree does not display its selection, when it is updated via binding of "selectedItems", where the property bound to is updated in response to a RESET of the data provider collection.
My workaround might interest some people. It is inspired by the pop-ups-with-presentation-manager pattern described by Theo "Iconara" Hultberg here: http://mate.asfusion.com/forums/topic.php?id=591 So, using BindingUtils.bindSetter, I have a function in the view which "observes" a status property in the presentation model. In the past, I have also used the Observe tag from Adobe consulting for this sort of thing. The observing function does the selection updating (though tree.selectedItems is still bound as well). The status property in the presentation model is updated when the collection is reset. In order to get this to work, I *still* had to wrap the view-based selection updating in a callLater(), which I hate, but such is life.
