Thanks Matt, I kept trying last night and this also works:
// Import the TreeNode.
import mx.controls.treeclasses.TreeNode;
// Create a data provider variable.
var treeDP;
function resultHandler(result)
{
var XMLStr:XML;
treeDP = new TreeNode();
XMLStr = new XML(result);
treeDP=XMLStr.firstChild.childNodes;
}
<mx:Tree labelFunction="lblFuncCode" dataProvider="{treeDP}" >
</mx:Tree>

Please respond to
flexcoders
You basically can write a quick function as a workaround:
function getChildNodes(xml):Array
{
return xml.firstChild.childNodes;
}
dataProvider="{getChildNodes(XMLStr)}"

Subject: [flexcoders] XML as dataprovider : Changes to unknown property,
childNodes, will not be detected.
I am using a Remote object that returns a string in a XML format, and
converting this string to XML by using
XMLStr = new XML(Str)
I then use XMLStr as dataProvider in a Tree.
<mx:Tree labelFunction="lblFuncCode"
dataProvider="{XMLStr.firstChild.childNodes}" >
</mx:Tree>.
The results are displaying OK, but I get a warning message:
Changes to unknown property, childNodes, will not be detected
I think I understand that this means that if I change XMLStr that change
will not be reflected on my Tree. I read this data at the beginning and I
don't expect the data to change. This is mainly a look-up.
How can I avoid this warning?
