Thanks, Matt, for your answer, which saved me a lot of time. I see the
answer is in the MM flexfaq, but somehow I missed it.

Subject: RE: Get selected tree node for dynamically created tree
You need to use node.getProperty("label") not .attributes, this way your
code will work regardless of how the dataProvider was specified.

Subject: [flexcoders] Get selected tree node for dynamically created
tree
First time creating trees in Flex. Can someone explain how to find the
selected tree node on a tree that has a data model created
programmatically? I create my data model as shown below (example from
Flex ActionScript Language Ref 1.5). The tree is displayed correctly.
When I try to use the nodeOpen event on my Tree control, however,
selectedNode is undefined. Event.node.attributes.label and
event.node.attributes.data are also undefined. However, if I use an
mx:XML dataprovider as most tree usage examples do, these attributes are
not undefined.
Code to create model:
var treeDP;
treeDP = new TreeNode();
var root = treeDP.addTreeNode("root","0");
root.addTreeNode("node 1 ","1");
root.addTreeNode("node 2","2");
var node3 = root.addTreeNode("node 3","3");
node3.addTreeNode("node 3-0", "3-0");
node3.addTreeNode("node 3-1", "3-1");
Tree Control:
<mx:Tree id="indTree" dataProvider="{treeDP}" height="100%"
change="treeSelected( event );"
nodeOpen="nodeOpenEvt(event);" ></mx:Tree>
Thanks for any help you can provide,
