Sencha touch form panel is not showing

Question

For some reason my form panel isn't showing. Can anyone help? I'm a newbie so sorry if this is obvious! It was build with Sencha Architect but I can't understand why no fields are showing in the form?...

Ext.define('MyApp.view.Login', {
    extend: 'Ext.Container',

    config: {
        layout: {
            type: 'vbox'
        },
        items: [
            {
                xtype: 'titlebar',
                docked: 'top',
                title: 'My Title'
            },
            {
                xtype: 'toolbar',
                docked: 'top',
                items: [

                    {
                        xtype: 'button',
                        text: 'Call'
                    },
                    {
                        xtype: 'button',
                        text: 'Email'
                    }                       
                ]
            },
            {
                xtype: 'container',
                flex: 1,
                border: 2,
                items: [
                    {
                        xtype: 'formpanel',
                        styleHtmlContent: true,
                        items: [
                            {
                                xtype: 'fieldset',
                                title: 'MyFieldSet',
                                items: [
                                    {
                                        xtype: 'textfield',
                                        label: 'Field'
                                    },
                                    {
                                        xtype: 'textfield',
                                        label: 'Field'
                                    }
                                ]
                            }
                        ]
                    }
                ]
            }
        ]
    }

});

Change the layout of your Login view from vbox to fit. Then set the layout of the container that contains your formpanel to fit also.
