Picker items not showing in 2.1.0

[zippo_yp]

I have a question about the Picker in the sencha touch 2.1.0, it seems a bug to me.
and this is my code in my controller, triggered by a button action.

var picker = Ext.Viewport.add( 
                                   {           
                                       xtype: 'picker',            
                                       height : 500,            
                                       doneButton: 'Choose',            
                                       cancelButton: true,            
                                       toolbar: {                
                                                       ui: 'light',                
                                                       title: 'Choose a Customer'            
                                      },            
                                      slots: [                   
                                                  {                        
                                                     name : 'customer',                        
                                                     title: 'Customer',                       
                                                      data : [                            
                                                                  {text: 'Test1', value: 50},                            
                                                                  {text: 'Test2', value: 100},                            
                                                                  {text: 'Test3', value: 200},                            
                                                                  {text: 'Test4', value: 300},                            
                                                                  {text: 'Test5', value: 300},                            
                                                                  {text: 'Test6', value: 300}                       
                                                                ]                    
                             }           
                   ]        
    }); 

and no matter how I set the the slots (in config and out of config), the slots items wont show up! this is the screenshot.

and the same code, if I use ST 2.0.1, it will show up without problem. like below

I also found, in the ST 2.1.0, if I put the slots into the config, then picker.getSlots() wont return any items, but if it is outside of config, then getSlots() does return the items, is it supposed to be in config??

Using your code with 2.1.0 (no custom CSS) it works for me:
