Hi, is there a way to prevent the current view be destroyed on navigation.pop() ?

(actually it is happening on backButton tap)

//create a a list
var newList = Ext.create('MyApp.view.Module.List', {
id: 'listId',
}); //get the list var list =Ext.getCmp('listId'); //asume nav is a navigation.view nav.push(list); nav.pop(); Ext.getCmp('listId'); --> now it is undefined
I would like to keep that specific instance alive,
