I create a treepanel and I and create `store` like

```
          var store = Ext.create('Ext.data.TreeStore', {
            autoload: false,
            proxy: {
                type: 'ajax',
                url: 'data.php',
                reader: {
                    type: 'json',
                    root: 'results'                 
                }
            }
          });

```

my server print json look like

```
{ "results": 
    [
    { id : '1' , text : '1', expanded: true, 
        children :[
            { id : '5' , text : '5', leaf:true},
            { id : '6' , text : '6', leaf:true}
        ]
    },
    { id : '2' , text : '2', leaf:true},
    { id : '3' , text : '3', leaf:true},
    { id : '4' , text : '4', leaf:true},
    { id : '7' , text : '7', leaf:true},
    { id : '8' , text : '8', leaf:true},
    { id : '9' , text : '9', leaf:true},
    { id : '10' , text : '10', expanded: true, 
        children :[
            { id : '11' , text : '11', leaf:true},
            { id : '12' , text : '12', leaf:true}
        ]
    }
    ]
}

```

But when i run my code, i see firebug and that always run `GET http://localhost/example/data.php...` never stop :(

and my tree is added so much double 

How to fix that thank

**Edit**

In real i define my treepanel with alias and using it as `xtype`

But i create new example and get same problem.
Here is my js

```
var store = Ext.create('Ext.data.TreeStore', {
            autoload: false,
            proxy: {
                type: 'ajax',
                url: 'data.php',
                reader: {
                    type: 'json',
                    root: 'results'                 
                }
            }
        });

        Ext.create('Ext.tree.Panel', {
            title: 'Simple Tree',
            width: 200,
            height: 150,
            store: store,
            rootVisible: false,
            renderTo: Ext.getBody()
        });

```

And here is my `data.php`

```
echo "
{
    'success': true, 
    'variable': 100, 
    'results': 
    [
    { id : '1' , text : '1', expanded: true, 
        children :[
            { id : '5' , text : '5', leaf:true},
            { id : '6' , text : '6', leaf:true}
        ]
    },
    { id : '2' , text : '2', leaf:true},
    { id : '3' , text : '3', leaf:true},
    { id : '4' , text : '4', leaf:true},
    { id : '7' , text : '7', leaf:true},
    { id : '8' , text : '8', leaf:true},
    { id : '9' , text : '9', leaf:true},
    { id : '10' , text : '10', expanded: true, 
        children :[
            { id : '11' , text : '11', leaf:true},
            { id : '12' , text : '12', leaf:true}
        ]
    }
    ]
}";

```
