Prior to this patch, columnar frames would always write multi-valued columns if the input column had hasMultipleValues = UNKNOWN. This had the effect of flipping UNKNOWN to TRUE when copying data into frames, which is problematic because TRUE causes expressions to assume that string inputs must be treated as arrays. We now avoid this by flipping UNKNOWN to FALSE if no multi-valuedness is encountered, and flipping it to TRUE if multi-valuedness is encountered. -- This is an automated message from the Apache Git Service.
