title: Loading extJS Combo Remotely not Working
body: <p>This is my first bash at using extJS, and after a few hours of struggling, some things are working OK, except I have combo lists that I can't filter down to less than 2000 items in edge cases, so I'm trying to page the lists through remotely, but I must be doing something wrong.</p>
  
  <p>My data store and combo look as follows:</p>
  
  <pre><code>var remoteStore = new Ext.data.JsonStore({
          //autoLoad    : true,
          url         : 'addition-lists.aspx',
          fields      : [{name: 'extension_id'}, {name: 'extension'}],
          root        : 'extensionList',
          id          : 'remoteStore'               
      });
  .
  .
                          xtype         : 'combo',
                          fieldLabel    : 'Remote',
                          name          : 'remote',
                          displayField  : 'extension',
                          valueField    : 'extension_id',
                          mode          : 'remote', 
                          //pageSize      : 20,
                          triggerAction : 'query',  
                          typeAhead     : true,                    
                          store         : remoteStore,
                          anchor        : '95%'
  </code></pre>
  
  <p>The combo works loading locally, but as soon as I switch to remote it remains blank.</p>
  
  <p>My ASP.NET page returning the JSON is like this:</p>
  
  <pre><code>protected void Page_Load(object sender, EventArgs e)
  {
      Response.Clear();
      Response.Write(GetRemote());
  }
  </code></pre>
