             Summary: NPE in GoupingNod
                 Key: TEIID-1968
                 URL: https://issues.jboss.org/browse/TEIID-1968
             Project: Teiid
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: 7.7
            Reporter: Mark Addleman
            Assignee: Steven Hawkins


I get an NPE within Teiid's GroupingNode.initialize when executing the following SQL
SELECT XMLELEMENT(NAME metadata,
                  XMLFOREST(objectName as objectName),
                  (SELECT XMLAGG(XMLELEMENT(name subTypes,
                                            XMLFOREST(subType)))
                   FROM chorus_metadata.property_filtered b
                   WHERE a.objectName=b.objectName
                   GROUP BY subType)
                 )
FROM chorus_metadata.property_filtered a
GROUP BY objectName
LIMIT 1

chorus_metadata.property_filtered is an internal materialized view.
