preserving expansion in DeferredTreeContentManager [message #556503]

I have tried to do this by creating my own subclass of the DeferredTreeContentManager, and after the children are added to the tree, I try to restore expansion, but I can only get one level deep - the problem is that I can only get expansion to one level deep when I use TreeViewer#setExpandedState.
If I have a tree path of depth 4 and I want to expand to the 3rd element, only the root of the tree is expanded because the retrieval of the other children is not immediate and on a job - the attempt to preserve expansion shows only the placeholder element as a child and cannot expand further.
Is there a reliable way to do preserve expansion state when using deferred content provider?
