extJS中AsyncTreeNode使用多个loader

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

for ex:

 

代码

 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;}   

       

         dang dang dang dang.It's work now!well done!
