Setting the 'selectedItem' twice works around this flex tree bug.

      This works, and tree.selectedItem is not null after assignment:

var nodeToSelect:XML = this.tree.dataProvider.getItemAt(0) as XML;

this.tree.expandItem(nodeToSelect, true);

this.tree.selectedItem = nodeToSelect; // NOT NULL


But this doesn't, when the tree 'selectedItem' is set to an xml sub node: 

var node:XML = this.tree.dataProvider.getItemAt(0) as XML;

var nodeToSelect:XML = node.children()[0]; // valid value


        this.tree.expandItem(n2, true);

        this.tree.selectedItem = nodeToSelect; // NULL

How can I fix this?
