Hello together,
based on the Lazy loading nodes in TreeGrid example (
http://www.jeasyui.com/tutorial/tree/treegrid5.php) i have question about node with an empty children list. 
I have modified the data set for this example and add a node with an empty children list on the end
{
   "id":99,
   "name":"D",
   "size":"",
   "date":"02/19/2010",
   "children":[
   ]   
}
In the a attached picture (empty_folder1.jpg) you can see a folder icon for D.
If i remove the lazy load functionality by removing the loadFilter data-option from the html file i got this result (empty_folder2.jpg)
The you can see a file icon for D.
How i can defined which icon is display for a node with a children list without members (empty folder).
