    Default Unanswered: Cannot call method 'getMargin' of undefined

    Unanswered: Cannot call method 'getMargin' of undefined


    I've looked around and didn't find any solutions yet, so here's my q:
    I got a button and I want it to load a new panel when it's clicked.
    When i click it it says : Cannot call method 'getMargin' of undefined
    So I'm guessing he doesn't know what App.views.viewport is in the controller file

    app.js
    Code:
    Ext.regApplication({    name: 'App',
        defaultUrl: 'Home/index',
        layout: "card",
    
        launch: function()
        {
            this.views.viewport = new App.views.Viewport();
        },
    });
    viewport
    Code:
    App.views.Viewport = Ext.extend(Ext.Panel, {    fullscreen: true,
        layout: 'card',
        cardSwitchAnimation: 'slide',
        dockedItems: [
            {
                xtype: 'toolbar',
                title: 'ChinaTown',
                items: [
                    {xtype: 'spacer'},
                    new Ext.Button({
                        text: 'Bestellingen',
                        itemId:'bestellingOverzicht',
                        listeners: {
                            tap: function(){
                                Ext.dispatch({
                                    controller: 'Home',
                                    action: 'showCart',
                                    displayObject: new App.views.Cart(),
                                    animation: {
                                        type: 'slide',
                                        direction: 'down',
                                        duration: 500
                                    }
                                });
                            }
                        }
                    })
                ],
            },
        ]
    });
    controller
    Code:
    Ext.regController('Home', {
    showCart: function(options){
             
             App.views.viewport.setActiveItem(options.displayObject,options.animation);
        }
    
    });
    
    I feel kinda silly that it won't work, so can anyone push me in the right direction ?

    Two things come to mind right away... I wouldn't use new Ext.Button like you are, you should just be using config objects. What is App.views.Cart?
