The solution I found is to keep a dictionary with a UID for each tree node as the key, and the returned Class as the value. When the iconFunction is called, check to see if the a Class already exists for this node, and if so, use it. Otherwise, get the icon using the above prescribed way, and then store it off in the dictionary.

Also, I found that due to animation, sometimes the call to itemToItemRenderer returns null so you cannot call getClass, thus no icon is shown right away. To solve this, just check if it returns null, and if so, call
this.callLater(myTree.invalidateList);

I have the same problem as Vijay. The icons get downloaded and assigned to the tree but they only become visible when i move the mouse pointer over the icon location. Then if the tree gets re-rendered (eg a branch gets expanded), all the icons disappear and will only show if the mouse is moved over them again. It’s driving me crazy, I can’t find what causes the icons to not show in the first place. Any ideas ? getting desperate here.

if I use the mxml tree tag, the class work nice, but if the tree is dynamic crated, it will not work.

how do you use the iconFunction if the tree is being instance use actionscript i.e
var tree:Tree()=new Tree();
tree.iconFunction = myFunc;
private function myfunc(item:Object):Class{
how can I know the tree?
}

Correct. Use the renderer. You will have to change the IconUtility class to accept any type of object and not just a UIComponent though.

Okay got it … it should be Tree.itemToItemRenderer(data) and not simply data …
