Component creation multiple times

[Arekkk]

Hi guys,
I'm facing an issue with my viewport.

I'm trying to destroy an element that could appear back later, but an error occurs at this second instance.

        
               Ext.getCmp('superMain').destroy();
               Ext.Viewport.add(Ext.create('myapp.view.Log'));

Then later

        
           Ext.getCmp('superLog').destroy();
           Ext.Viewport.add(Ext.create('myapp.view.Main')); // id=superMain (destroyed before)

Can't go further...

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

Hope someone can help me
Thanks a lot

Do not use 'id' , your component is not a singleton (you create ,destroy and create again).

Ext.Viewport.add(Ext.create('myapp.view.Main',{itemId:'superMain'}));
Ext.Viewport.getComponent('superMain').destory();
Ext.Viewport.add(Ext.create('myapp.view.Log',{itemId:'superLog'}));
Ext.Viewport.getComponent('superLog').destroy();
Ext.Viewport.add(Ext.create('myapp.view.Main',{itemId:'superMain'}));

This isn't working... can't do a Ext.getCmp on it.

what's you mean? why you use Ext.getCmp?
I have tested it,only a spell error on my code.(destory ---> destroy )
