因为他们共享数据集（对象引用）。修改您的商店，如下所示：

Ext.define('ComplexTree', { 
    extend: 'Ext.data.TreeStore', 
    alias: 'store.complextree', 

    constructor: function (config) { 
     config = config || {}; 
     config.root = { 
      expanded: true, 
      children: [{ 
       text: 'test', 
       leaf: true 
      }, { 
       text: 'test2', 
       expanded: true, 
       children: [{ 
        text: 'test21', 
        leaf: true 
       }, { 
        text: 'test22', 
        leaf: true 
       }] 
      }, { 
       text: 'test3', 
       leaf: true 
      }] 
     }; 
     this.callParent([config]); 
    } 
});
