[Embed('item_bullet.png')]
private var ITEM_BULLET_ICON: Class;
<mx:Tree iconField="icon" />
<mx:dataProvider>
<mx:XML>
<node label="Node1" icon="Test2_ITEM_BULLET_ICON "/>
</mx:XML>
</mx:dataProvider>
</mx:Tree>
And what the heck is "Test2_ITEM_BULLET_ICON"? It's the actual name of the class created by the embed. You can see the name if you trace the variable ITEM_BULLET_ICON. The project name I used was Test2 so that's where that came from.
I think the problem here is that the ListBase class (which Tree inherits from) requires a reference to the class when specifying the icon. When I used a List component, the only way I got the icon to show up was to put the following in the Array dataprovider:
<mx:Object label="Item1" icon="{ITEM_BULLET_ICON}">
You can't do something like that for an XML dataprovider cause that XML is just seen as raw data, so you have to specify the name of the class to get it to work.
Meh...I just think it's broken. It certainly doesn't follow what the docs say...

Hi Jason,
Thanks for the reply. I really should have been more specific last
night when I posted this... I'm actually trying to define an icon
within the individual nodes using the "icon" parameter. I've defined
the Class as you have by embedding an asset, but when I try to
reference that asset like so:
[Embed(source='mypng.png')]
public var myCustomIcon:Class;
<mx:Tree iconField="icon" />
and within the dataprovider structure for the tree...
<node label="Node 1" icon="myCustomIcon" />
it gives me the error I described previously. What works in 1.5 does
not work in 2.0, although it's document the same... well actually, not
quite the same... the documentation for 2.0 still states that the
embedded asset be typed as String. So it works as a String in 1.5,
but I've tried both String and Class in 2.0 with no luck.
Thanks,
Brendan
