CFFORM - Tree - DragDrop

Já escrevi algumas matérias sobre tree, com códigos meus:
Ações e eventos
Tree.dataProvider com XML complexo
mx:Tree addNode/removeNode 2
mx:Tree addNode/removeNode

Ou lembretes sobre outras matérias:
mx:Tree

Mas percebi que nenhuma demonstra o uso de DragDrop, então implementei um pequeno script de exemplo para vocês, e o resultado pode ser observado no filme a seguir.

<cfform format="flash" name="form" onload="initDragDrop();">
<cfformitem type="script">
function initDragDrop(){
tree.dragEnabled = true;
lista.dragEnabled = true;
tree.multipleSelection = true;
lista.multipleSelection = true;
tree.addEventListener('dragEnter' , dragEnterEvent );
lixeira.addEventListener('dragEnter' , dragEnterEvent );
tree.addEventListener('dragDrop', dragCompleteEvent);
lixeira.addEventListener('dragDrop', dragCompleteEvent);

}
function dragEnterEvent(event){
var source = event.dragSource._data.source;
event.handled = source.__id == 'tree' ? true : ( event.target._name == 'tree' ? true : false );
}
function dragCompleteEvent(event){
var source = event.dragSource._data.source;
if(event.target._name == 'lixeira' && source.__id == 'tree'){
for(var i = _root.tree.selectedNodes.length-1; i>=0; i--){
_root.tree.selectedNodes[i].removeTreeNode();
}
}else if(event.target._name == 'tree' && source.__id == 'lista'){
if(event.target.selectedNode == null){
for(var i = 0; i < source.selectedItems.length; i++){
event.target.addTreeNode(source.selectedItems[i].label,source.selectedItems[i].data);
}
}else{
for(var i = 0; i < source.selectedItems.length; i++){
event.target.selectedNode.addTreeNode(source.selectedItems[i].label,source.selectedItems[i].data);
}
}
}
}
