************************************
If you want to set the defaultLeafIcon style to null in MXML, you could use the following snippet:
<mx:Tree id="tree"
dataProvider="{dp.league}"
defaultLeafIcon="{null}"
labelField="@label"
iconField="@icon"
showRoot="true"
width="320"
rowCount="9" />
Or, if you want to set the defaultLeafIcon style in ActionScript, you could use the following snippet:
<mx:Tree id="tree"
dataProvider="{dp.league}"
labelField="@label"
iconField="@icon"
showRoot="true"
width="320"
rowCount="9"
initialize="tree.setStyle('defaultLeafIcon', null);" />
