    Default Answered: How can I use singleton component?

    The pop() function in Ext.navigation.View seems to destroy the component that is poped.
    I want to reuse the component(without initialize), but it always calls initialize function.

    How can I do that?

    Code:
    Ext.define('Test.view.InfoPanel', {
      extend: 'Ext.Panel',
      xtype: 'infopanel',
      // singleton: true,  // this option causes problems because non-singleton components are in initialize function.
    
      initialize: function() {
        console.log('InfoPanel has been initialized.');
      }
      ...
    });
    
    // this code always calls initialize function.
    mainview.push({ xtype: 'infopanel' });

  2. You can set autoDestroy to false on the item. Then if you have singleton set to true it will create the component right away and you can push the class name, not xtype.
