Sending multiple records to the RExpression actor via a multiport input does
not work as expected.  With a single record, it behaves as expected.  With two
different records, it seems to drop the last column from each.  If the two
records come from the same source, the actor behaves as expected.  If the two
records come from different sources but contain the same data, the actor
behaves as expected.  With three different records, it seems to drop the first
and last column.  If the three records come from the same source, the actor
behaves as expected.  If the three records come from different sources but
contain the same data, the actor behaves as expected.  If only two of the three
records contain unique data, then the actor drops the last column from all
three.
