I have a Tree that has really deep levels (10+). When I keep expanding the TreeItem, the current TreeItem being expanding is focused but the scrollbar will not always make sure the item is in the center. Instead the scroolbar makes the item shows up at the bottom of the TreeViewer.
Way to reproduce:
1. Go to http://codefaces.org/http://github.com/jruby/jruby
2. Expand the tree to src/org/jruby/java/proxy/...
You will notice that the scroll bar always make sure the TreeItem in deep levels shown up at the bottom of the TreeView.
I am wondering what goes wrong with it.
Thanks,
Owen

Hi Owen,
did you test your code in RCP? If your code works as you expected in
RCP, bit not in RAP, it's probably a RAP bug. In this case, please feel
free to open a bugzilla with a snippet to reproduce it.
Thanks,
Ivan
