title: How to reload TreeStore?
body: <p>I have nestedlist with treestore. While loading first time the store is loaded perfectly and list is being displayed according to the store. When i click refresh button , my treestore should get reloaded with new data (with same data model as the first time) and nested list also need to be reloaded with new set of data.</p>
  
  <p>Below is my treestore definition</p>
  
  <pre><code>rightPaneStoreData = getFolderListData();
  
  rightPaneStore =new Ext.data.TreeStore({
  
     autoLoad:false,
  
     model: 'FIMT.models.rightPaneModel',
  
     root: rightPaneStoreData,
     proxy: {
  
     type: 'memory',
  
     reader: {
  
         type: 'tree',
         root: 'items'
         }
  
     },
     listeners: {
         datachanged: function(records){
             alert("datachanged");
             }
     }
  
     });
  
  rightPaneStore.load();
  </code></pre>
  
  <p>In Ext.data.JsonStore i have accomplished the same using store.loaddata() method. But i couldnt find loaddata() method for TreeStore. </p>
  
  <p>Kindly help me.</p>
