I am a relative Flex newbie (oldskool Flash 4-8 developer) and would appreciate any insight. I’ll be glad to include code samples of what you would think helpful.

Thansk again!

I also see:

2. No “shuffle” effect when reordering components on a potential drop and

///what is this doing?
var renderer:IUIComponent = _renderCache.associate(_items);

//this is the really confusing part to me, especially the syntax of IDataRederer(rederer) …
//after looking at the IDataRederer interface it doesnt look like this should be possible… what am I missing?
IDataRenderer(renderer).data = _items;

//adds it to a list of renderers for later reference
_renderers = renderer;

//add this to the display list, any special reason for having to put it in a DisplayObject() call?

any further explanation?

Thank you for posting such an awesome component. That code is pretty rich and deep, and to be hoenst, I am not sure that I understand it all! Especially this part, I know that this is what adds all the items (images) to the display list, but I am not understanding the syntax and reasoning behind it… here is the code.

//_renderCash is an instance of Adobe’s AssociativeInstanceCache.as
//what exactly does this do, and why do we need to open and close the associations?
_renderCache.beginAssociation();
