How can I create downloadable product along with simple and configurable product ? 

If I leave blank than getting error and If i assign sources to product than checkout displays shipping step and shipping method can't load due to its virtual/downloadable product. Cant able to complete payment.

Any ideas ? `I ain't sure It is bug or I'm missing something` ? Any help would be appreciated.
