That happens because the resources required to populate the listbox are received through the RPC call and are asynchronous. When you make a call for the resources, your code does not stop to wait for the response from the server, so when trying to populate your listbox you create it and fill it with with nothing because the RPC call has not returned yet.
When creating your GUI elements, first make the RPC call to get your resources, then create your GUI in the onSuccess method of the RPC call. That way you will have all your resources when you are creating your GUI elements.
