If you want to open the root tree node, use the root node of the dataProvider xml. Are you binding or using a result handler?

Yeah, I saw that, but how do I get "item"?  That's what's throwing the error

tree.selectedItem = 0  - I get an error

Thoughts?

Use tree1.expandItem([item:Object],openorclose:Boolean).

 

item:Object would be the root node of the xml dataProvider.

This no longer works in beta3, any updates on how it's actually done?

 

Expanding a tree node

By default, the 

 
 
Tree
 control displays the root nodes of the 

 
tree
 when it first opens. If you want to expand a node of the 


 
tree
 when the 

 
tree
 opens, you can use the 
setIsOpen() method of the 

 
Tree
 control. The following example calls this method as part of the handler for the 
creationComplete
 event to expand the first root node of the 

 
tree
: <mx:Script>




    <![CDATA[




        function init

 
Tree
(){




            

 
tree
1.setIsOpen(

 
tree
1.getNodeDisplayedAt(0), true);




        }




        ]]>




    </mx:Script>









<mx:


 
Tree
 id="

 
tree
1" ... creationComplete="init

 
Tree
();" >




    ...




</mx:


 
Tree
>
