Hi,
I had this problem also, it seems that if you use the databinding
functionality, then you will have to detect when the tree is fully
loaded before setting a node to open.
I did a sort of hack to achieve this. I used the following to listen
to the tree's list items update complete. ( This will fire for each
item in your tree so you will have to put some logic to handle this
behavior in your treeDataChangedHandler code ) note: it will also fire
each time you expand the tree and more nodes are made visible.
tree.addEventListener(FlexEvent.UPDATE_COMPLETE, treeDataChangedHandler);
In my treeDataChangedHandler function, I am expanding the tree and
selecting the first node.
private function treeDataChangedHandler(event:Event):void
{
tree.expandChildrenOf(tree.firstVisibleItem,true);
tree.selectedItem = tree.firstVisibleItem;
}
I know that this is a bit of a hack and My wish is for this
functionality to be part of the built-in functionality for controls.
Cheers,
Tim
