I've been struggling trying to figure out how to get Tree.expandItem()
to work.
For example, I have this mxml:
<mx:Tree id="tree1" showRoot="true" width="180" height="100%"
verticalScrollPolicy="off">
<mx:dataProvider>
<mx:XML format="e4x">
<node label="Configuration" id="conf"
creationComplete="tree1.expandItem(conf, true);">
<node label="Main Config"/>
<node label="Helper Apps"/>
</node>
</mx:XML>
</mx:dataProvider>
</mx:Tree>
The intention is to have the "Configuration" node opened when the tree
is displayed. But the tree displays with that node closed.
