TreeViewer with ILazyTreeContentProvider [message #757356]

I have a TreeViewer with SWT.VIRTUAL and an ILazyTreeContentProvider.
It has ~1000 top level nodes. I am trying to add a search so that the user can move right to the desired node. I'm calling expandToLevel(element, 1) on the searched for node. It works fine when the desired node is already visible.
But when the the searched for node is farther down the list, and not currently visible, it does not become visible.
Is there a way to change the view of the tree so that a specified root node is visible?

Thanks,

Have you tried TreeViewer.reveal(item)?

Yes, I tried reveal(), update(), refresh() - but they didn't help...
Thanks,
