TouchCalendarView day mode requires calling setMode('day')

[gabegorelick]

In the following code, the calendar is not scrollable (there may be other layout issues, but that is the one I noticed first):

Ext.setup({
    onReady: function() {
        calendarView = new Ext.ux.TouchCalendarView({
            mode: 'day'
        }); 
        var calendarPanel = new Ext.Panel({
            fullscreen: true,
            layout: 'fit',
            items: [calendarView]
        });
    }
});

Adding a call to setMode('day') after the panel is created makes it work.
