title: Ext.data.Store does not reload immediately
body: <p>when trying to populate A ENTIRE GRID using the ajax from a combobox in the select listener when i try to recall or reload the datastore i'm still getting the old values, instead of the new ones. i have to get the new values because according to the parameter selected in the combobox the textfields and the others editor will populate with that json data read from server using ajax, accoding with another combobox that fetch remote data</p>
  
  <pre><code>var cm = new Ext.grid.ColumnModel({
