There is a typo: ` <link rel="stylesheet" href="../../css/dock-whell.css"> ` should be ` <link rel="stylesheet" href="../../css/dock-wheel.css"> ` and there is a missing "," at the end of this function: `onShowDialog:function(self, dialog){ console.log('onShowDialog: ', self, dialog); localStorage.setItem(storeKey, dockManager.saveState()); },` Cheers.
