    Default Tree does not load at IE7 using the ext-3.0-rc2

    Hi, I am pretty confused as I cannot get the Tree to load. I had an application and right now I am trying to put it at a desktop style. I have a tree which I cannot get loaded at IE7. The FF and Opera do good job but IE!
    I tried to make it as simple as it can be and wrote:
    PHP Code:
    Ext.onReady(function(){

               var testTree = new Ext.tree.TreePanel({
                   id: 'testtree',
                   border: false,
                   rootVisible: false,
                   lines: true,
                   singleExpand: true,
                   loader: new Ext.tree.TreeLoader({
                       dataUrl:'<?=DIR_TO_DESKTOP;?>treeJSON.php'
                       }),
                   root: new Ext.tree.AsyncTreeNode()
               });
               testTree .render('tree');
    });
    Server respond is:

    PHP Code:
    [{
        
    text'To Do',
        
    cls'folder',
        
    children: [{
            
    text'Go jogging',
            
    leaftrue,
            
    checkedfalse
        
    },{
            
    text'Take a nap',
            
    leaftrue,
            
    checkedfalse
        
    },{
            
    text'Climb Everest',
            
    leaftrue,
            
    checkedfalse
        
    }]
    },{
        
    text'Grocery List',
        
    cls'folder',
        
    children: [{
            
    text'Bananas',
            
    leaftrue,
            
    checkedfalse
        
    },{
            
    text'Milk',
            
    leaftrue,
            
    checkedfalse
        
    },{
            
    text'Cereal',
            
    leaftrue,
            
    checkedfalse
        
    },{
            
    text'Energy foods',
            
    cls'folder',
            
    children: [{
                
    text'Coffee',
                
    leaftrue,
                
    checkedfalse
            
    },{
                
    text'Red Bull',
                
    leaftrue,
                
    checkedfalse
            
    }]
        }]
    },{
        
    text'Remodel Project',
        
    cls'folder',
        
    children: [{
            
    text'Finish the budget',
            
    leaftrue,
            
    checkedfalse
        
    },{
            
    text'Call contractors',
            
    leaftrue,
            
    checkedfalse
        
    },{
            
    text'Choose design',
            
    leaftrue,
            
    checkedfalse
        
    }] 
    All I can see at IE is like shown in the picture. Child nodes do not load.
    Please, help to get to know what is happening.
    Thank you
    Nick

    Default CLOSED

    found this:
    PHP Code:
    Ext.override(Ext.tree.TreeLoader, {
        
    runCallback: function(cbscopeargs){
            if(
    Ext.isFunction(cb)){
                
    cb.apply(scopeargs || []);
            }
        }
    }); 
    It gave the life to a tree.
    Thank you
    Nick
