    Default Exception is thrown when carousel is destroyed

    Exception is thrown when carousel is destroyed


    REQUIRED INFORMATION
    Project Type:
    • Touch 2.2.0
    Description:
    • When destroying a carousel an exception will be thrown if the carousel contains items that has been flipped.
    Steps to reproduce the problem:
    • Create a carousel with a couple of panels with card layouts.
    • Flip one of the cards.
    • Destroy the carousel.
    The result that was expected:
    • The carousel should be destroyed and no exception should be thrown.
    The result that occurs instead:
    • Exception is thrown: Uncaught TypeError: Cannot call method 'getParent' of undefined Flip.js:38.
    HELPFUL INFORMATION
    Screenshot, Project, or Video:
    • See the app.js example below. Use it in a newly generated 2.2.0 app to trigger the exception.
    Code:
    // DO NOT DELETE - this directive is required for Sencha Cmd packages to work.
    //@require @packageOverrides
    
    
    //<debug>
    Ext.Loader.setPath({
        'Ext': 'touch/src',
        'test': 'app'
    });
    //</debug>
    
    
    Ext.application({
        name: 'test',
    
    
        requires: [
            'Ext.MessageBox',
            'Ext.Carousel'
        ],
    
    
        views: [
            'Main'

            var cards = Ext.create('Ext.Carousel', {
                fullscreen : true,
                items: [
                {
                  layout: 'card',
                  items: [
                    { html : 'Front' },
                    { html : 'Back' }
                  ]
                },
                {
                  layout: 'card',
                  items: [
                    { html : 'Front' },
                    { html : 'Back' }
                  ]
                }
                ]
            });
    
    
            // If you comment away this line the exception won't be thrown.
            cards.getAt(1).animateActiveItem(1, { type: 'flip' });
    
    
            Ext.defer(function () {
              cards.destroy();
            }, 3000);
        },
    
    
        onUpdated: function() {
            Ext.Msg.confirm(
                "Application Update",
                "This application has just successfully been updated to the latest version. Reload now?",
                function(buttonId) {
                    if (buttonId === 'yes') {
                        window.location.reload();
                    }
                }
            );
        }
    });
