How to move between panels in Sencha touch

When moving between panels I get the following error

[WARN][Ext.Component#constructor] Registering a component with a id (`logOutButton`) which has already been used. Please ensure the existing component has been destroyed (`Ext.Component#destroy()`.

I can go back to the previous screen but the cannot go forward again without getting the above error.

To combat this I have tried using the code below, but it does not work. Can anyone help me out?

var loginView = Ext.getCmp('login');
    if(!loginView){
       Ext.getCmp('loginTest2').destroy(); 
      loginView = Ext.create('com.view.Login');
  }

  Ext.Viewport.setActiveItem('login');

I also tried:

if(Ext.getCmp('login')){
     Ext.Viewport.setActiveItem('Login');
  }else{

    Ext.Viewport.setActiveItem(Ext.create('com.view.Login'));
  }

Neither of these work and result in the same error and a blank screen. I am using Sencha Touch 2.

To avoid this error do not use id for button or any other item instead of id use action config for button or use item id .to destroy a component using itemId simply use this`

Ext.ComponentQuery.query('list[action=diaryselectlist]')[0].destroy();

above it just destroying a list to whom i gave action not id you can give itemId instead of action in this .. hope you will enjoy this

we can simply use following line to navigate from one panel to another..

Ext.Viewport.animateActiveItem({ xtype: "cat" }, { type: "slide", direction: "up" });

here, xtype is that we can define for the panel we want to display, like this...,

Ext.define('BeLocal.view.LeftCurveList', {
       extend: 'Ext.Panel',

       **xtype: 'cat',**

       config: {

       items: [
               {
               xtype: 'toolbar',
               docked: 'top',
               width: '100%',
               padding:0,
               title: 'BeLocal Places',
               items:[{
                      xtype: 'button',
                      ui: 'back',
                      text: 'Back',
                      ]
               },

            ]
       }
       });
