Hi!
Maybe you could override inputChanged(Viewer, Object, Object) in your
IContentProvider and register an ITreeViewerListener that calls "update"
on the viewer every time the expansion state of an element changes.
(I know, this should be done in the label provider instead, but
unfortunately only the content provider gets access to its viewer)
