You could also use nested Array and Object literal syntax to do this in
one statement:
myTree.dataProvider =
[
{ label: "Top level", children:
[
{ label: "First" },
{ label: "Second" }
]
},
{ label: "Another top level" }
];
When you set the dataProvider do an Array, it gets converted to an
ArrayCollection automatically.

Subject: [flexcoders] Re: Trees and ActionScript
As is usually the case, I spend all my time trying to figure out the
solution to the problem and then finally give up and post a message.
Then five minutes later I figure out the solution. ;)
Here's an example:
obj = new Tree();
dataProvider = new ArrayCollection();
var o1:Object = new Object();
o1.label = 'Top Level';
dataProvider.addItem(o1);
var o1a:ArrayCollection = new ArrayCollection();
o1.children = o1a;
var o1a1:Object = new Object();
o1a1.label = 'First';
o1a.addItem(o1a1);
var o1a2:Object = new Object();
o1a2.label = 'Second';
o1a.addItem(o1a2);
var o2:Object = new Object();
o2.label = 'Another top level';
dataProvider.addItem(o2);
obj['dataProvider'] = dataProvider;
Hope that helps someone some day. ;)
