ExtJS的庫而不網址TreePanel中

Question

型號：

Ext.define('Product', { 
    extend: 'Ext.data.Model', 
    fields: [ 
     {name: 'product',  type: 'string'}, 
//  {name: 'active',  type: 'string'}, 
     {name: 'balance', type: 'string'} 
    ] 
}); 

商店：

var store = Ext.create('Ext.data.TreeStore', { 
     model: 'Product', 
     proxy: { 
      type: 'ajax', 
      url: 'treegrid.json' 
     }, 
     folderSort: true 
    }); 

的TreeGrid：

var tree = Ext.create('Ext.tree.Panel', { 
     title: 'Core Team Projects', 
     width: 500, 
     height: 300, 
     renderTo: Ext.getBody(), 
     collapsible: true, 
     useArrows: true, 
     rootVisible: false, 
     store: store, 
     multiSelect: true, 
     singleExpand: true, 
     //the 'columns' property is now 'headers' 
     columns: [{ 
      xtype: 'treecolumn', 
      text: 'Ürün', 
      flex: 2, 
      sortable: true, 
      dataIndex: 'product' 
     },{ 
      text: 'Bakiye', 
      flex: 1, 
      dataIndex: 'balance', 
      sortable: true 
     }] 
    }); 
    this.add(tree); 
    this.doLayout(); 

我的問題： 我能載入我的TreeGrid與此網址json商店。但我想加載解碼的json對象，它來自服務器。類似下面：

商店：

var store = Ext.create('Ext.data.TreeStore', { 
     model: 'Product', 
     root: inData, 
     folderSort: true 
    }); 

INDATA：

{"text":".", 
"children":[ 
{"product":"Mevduat","balance":"15000","expanded":"true","children":[ 
     {"product":"Vadesiz Mevduat","balance":"7000","expanded":"true","children":[ 
     {"product":"Vadesiz Hesap","balance":"3500","leaf":"true"}, 
     {"product":"fk Hesap","balance":"3500","leaf":"true"} 
     ] 
    }, 
    {"product":"Vadeli Mevduat","balance":"8000","expanded":"true","children":[ 
     {"product":"Kirik Vadeli Hesap","balance":"3000","leaf":"true"}, 
     {"product":"Birikimli Gelecek Hesabı","balance":"5000","leaf":"true"} 
    ]}] 
}, 
    {"product":"Bireysel Krediler","balance":"40000","expanded":"true","children":[ 
     {"product":"Konut Kredisi","balance":"15000","leaf":"true"}, 
     {"product":"Arsa Kredisi","balance":"25000","leaf":"true"} 
    ] 
}]} 

但是，如果使用INDATA JSON對象，我的樹面板不顯示文本。

使用memory proxy和root配置：

var store = Ext.create('Ext.data.TreeStore', { 
    model: 'Product', 
    proxy: { 
     type: 'memory' 
    }, 
    root: inData, 
    folderSort: true 
});
