I’m on Rails 2.0.2, and can’t get Ajax working with EXTJS.  
I’m trying this from the EXTJS tutorial:

```auto
Ext.onReady(function(){
  Ext.get('okButton').on('click', function(){
    var msg = Ext.get('msg');
    msg.load({
      url: '/users/ExtStart_ajax',
      params: 'name=' + Ext.get('name').dom.value,
      text: 'Updating...'
    });
    msg.show();
  });
});

```

I suspect that the URL I am using is not correct because when I ckick  
the ‘okButton’, I simply hang with the spinner going forever. But I  
do have a function called ‘ExtStart\_ajax’ in my users\_controller.rb.

Any help greatly appreciated!

Nevermind – I figured it out.
