Eclipse JFace TreeViewer level auto expansion doesn't work

Question

According to the Eclipse documentation TreeViewer.setAutoExpandLevel(3) means that top-level elements are expanded, and their children, but not grandchildren.

I used that in my code, but after setting the input the tree is not auto-expanded, neither on OS X nor on Linux. Expanding the tree manually (via mouse) works flawlessly. Am I missing anything?

Looks like this isn't going to be changed.
