extJS中AsyncTreeNode使用多个loader

when I use AsyncTreeNode,I found that AsyncTreeNode's loader can't override

for ex:

 

 1 var tree = new Ext.tree.TreePanel({
 2 xtype: 'treepanel',
 3 el:'tree',
 4 animate:true,
 5 autoScroll:true,
 6 containerScroll:true,
 7 autoHeight: true,
 8 loader: {dataUrl: "http://server/webapps/treePanel.jsp"},
 9 root:
10 {
11 text: 'root2',
12 draggable:false, // disable root node dragging
13 loader: {dataUrl: "http://server/webapps/treeNode.jsp"},
14 id:'root',
15 expanded: true
16 }
17 });
18 tree.render();
19 });
20 

 

when I click root2 Node,"http://server/webapps/treeNode.jsp" never gets called。

 

check source code,maybe there is a bug

 createNode:function(attr)

......

if(this.applyLoader!==false){attr.loader=this;}----------------set treePanel's loader to node's loader,the scope of "this" maybe point to treepanel.

 

so I changed:

if(this.applyLoader!==false){if(attr.loader==null)attr.loader=this;}
