Stephan Ewen commented on FLINK-940:
------------------------------------
Can you attach the code of the program with that problem?
I have written a program that uses a co group with the solution set, taking the solution set as the second input, and it works fine.
> DeltaIteration coGroup at SolutionSet doesn't find values
