Maxym Pendyshchuk commented on HHH-2225:
----------------------------------------
few days gone with no success with the same issue... Writing "The SQL fragment can be as complex as you want and even include subselects." in documentation now looks like a joke, I tried both HQL and native sql as simple as possible, and all the time I get NullPointerException...
Is here any progress? Any plans?
