Julian Hyde updated CALCITE-2708:
---------------------------------
    Description: 
In MATCH_RECOGNIZE, validator must ensure that arguments to a user-defined 
aggregate function (UDAF) come from a single pattern variable.

Query:
{code:java}
SELECT *
FROM Ticker
MATCH_RECOGNIZE (
  ORDER BY proctime
  MEASURES
    udagg(A.price + B.tax) AS taxedPrice
  PATTERN (A B)
  DEFINE
    A AS A.symbol = 'a'
) AS T
{code}
should fail with ValidationException, because udagg is applied to different 
pattern variables.
