Bug in GroupBy node


I have noticed that the GroupBy node has a bug in it. The bug only seems to surface when you have the "Retain Row Order" box ticked, and the input into the GroupBy node only consists of one row.

The bug produced is that it randomly deletes one of the columns, and returns this error;

ERROR GroupBy DataSpec generated by configure does not match spec after execution.


Hello Simon,
thanks a lot for the bug report it will be fixed in the next KNME version.
