Update:
Heard back from the author at the cited post. The issue was not that I misquoted the author in the passages that I cited, but rather I did not convey the full scope of the author’s criticisms of Cairngorm. The passages I quoted focused on criticisms of Singletons (which are one of the major criticism levelled at Cairngorm), but the author has also made criticisms of Cairngorm that go beyond its use of Singletons. You can read the author’s thoughts on Cairngorm and other topics on this blog http://blog.iconara.net.

The title of the book is Learning JQuery 1.3 and here are some of the things that impressed me so far. Firstly, the Forward of the book is written by John Resig the Creator of jQuery and he gives very high praise to the authors. Secondly it includes sections on creating such things as an image carousel and a headline rotator, so we are not talking about a book on just the mechanics of JQuery, you actually get to see practical applications of JQuery.

You can find a sample chapter of the book here and more details on the publisher’s site here.

I have placed links to this book on the Development Resources and Book Recommendations as well.

private function expandTree():void{
for (var i:int = 0; i < thisTree.dataProvider.length; i ++){
thisTree.expandChildrenOf(thisTree.dataProvider[i], true)
}
}
private function collapseTree():void{
for (var i:int = 0; i < thisTree.dataProvider.length; i ++){
thisTree.expandChildrenOf(thisTree.dataProvider[i], false)
}
}

When looking at this, I noticed the name of the function is expandChildrenOf, which to me inferred it would expand all of the children of the given node. So I looked into a bit further and the description for this function in the documentation states (http://livedocs.adobe.com/flex/2/langref/mx/controls/Tree.html#expandChildrenOf()):

expandChildrenOf () method
public function expandChildrenOf(item:Object, open:Boolean):void

Opens or closes all the tree items below the specified item.
Parameters
item:Object — the starting item

open:Boolean — toggles an open or close operation

So if that is the case and I pass this function the root node of the dataProvider such as in the following:

this.myTree.expandChildrenOf(this.myTree.dataProvider[0],true);

It did as expected and expanded all of the nodes under the root node. No loop required.
