Reproducible with Controls Demo -> Tree tab.
1. Check "VIRTUAL"
2. Click "Deselect all"
3. Set items count to 300.
4. Mouse click (to select) one of the items
5. Use arrow down key to scroll the tree.
You will get a NPE like this:
java.lang.NullPointerException

When the selected item on the client is not yet materialize the item id sent by the client is - <parentId>#<itemIndex>. Changed ThreeLCA to respect this format. Changes are in CVS HEAD.
