Thanks..

var loader:URLLoader = new URLLoader();
loader.addEventListener( Event.COMPLETE, handleComplete );
loader.load(new URLRequest(“sampleData.xml”));

private function handleComplete( event:Event ):void {
var example:XML = new XML( event.target.data );
Model.instance.opAreaXMLList = example.children();

1178: Attempted access of inaccessible property _dropData through a reference with static type mx.controls:Tree.

I say that this is possibly more robust because although your solution gets around the crash, I almost always get an incorrectly-rendered tree as someone above has also mentioned.

Hope this helps!

I not sure about your case. Couple suggestions you could try.

Sometimes a callLater() in the right spot can do wonders.

Perhaps test for a bool variable that signified the data loading, if data is loading then try a preventDefault() in the events itemOpen or itemClose combined with a callLater to give the data time to properly load, the call could perhaps be on the same event i.e.

callLater(yourItemCloseHandler,[event]);

Or perhaps test when you open the folder. If data is not already loaded for that folder then don’t use animation.

expandItem(_lastNodeOver.data,true,false);

Keeping in mind these suggestions are without knowing any details about your specific implementation.

BTW, the enginner of Adobe had made a promise at November 2006 at Flexcoders to upgrade access to _dropData property to public
http://www.mail-archive.com/flexcoders@yahoogroups.com/msg46023.html

ps..
I am currently fighting with myTree.calculateDropIndex method, if you are interested in my adventures with Flex 2 Tree, I can provide you with the link to my demo app.

Oops. I’d not thought about that at all. Just assumed everyone had/would have upgraded.

Appreciate the heads up and the nice comment.

I had actually used that originally for getting at the drop location, and then decide to go back the old way. Even worse it’s not used in the sample at all. You can safely remove that property and it’ll work.

Warning I’ve not tried it on Flex 2.0

My posts will from now on have the Flex 2.0.1 in the title.

That said I’ll update the code online immediately.

Thanks again.

EDIT: Code updated. I don’t see a real need for yet another update post.

I want to clarify for the rest of the folks that this Spring Loaded Folders Tree component works correctly only with *Flex 2.0.1 SDK*, just released by Adobe at January 2007.
http://www.adobe.com/support/flex/downloads_updaters.html

If you are still using Flex 2.0 SDK, you will receive the following error in Flex Builder why compiling Spring Loaded Folders Tree:
———
1178: Attempted access of inaccessible property _dropData through a reference with static type mx.controls:Tree. AudiooFileBrowser/src/com SpringLoadedTree.as
———

In Flex 2 SDK the Tree.as the property _dropData was declared as private.

ps
Jason, it is nice to see this new great effort from you targeting at the new useful developments at Flash sphere. I remember your efforts to build RTE in Flex 1.5, it was also a good try
