Yes, CDI does its own extension of VaadinServlet so you can only use one or the other. This is not a hugely complicated add-on, though, so it’s probably possible to extend VaadinCDIServlet in a similar way in your local environment (sources can be found in GitHub, see the Links section). I’m afraid I don’t have time to look into it myself right now, I’m just about to start a vacation, but let me know if you can’t get it working.
