[jira] [Created] (FLINK-7955) Rowtime attribute cannot be aggregated in group window of stream Table API

Fabian Hueske created FLINK-7955:
------------------------------------

             Summary: Rowtime attribute cannot be aggregated in group window of stream Table API
                 Key: FLINK-7955
                 URL: https://issues.apache.org/jira/browse/FLINK-7955
             Project: Flink
          Issue Type: Bug
          Components: Table API & SQL
    Affects Versions: 1.3.2, 1.4.0
            Reporter: Fabian Hueske


The following query fails with a {{NullPointerException}}:

{code}
val windowedTable = table
      .window(Tumble over 5.milli on 'rowtime as 'w)
      .groupBy('w, 'word)
      .select('word, 'rowtime.count, 'w.start, 'w.end)
{code}

Equivalent SQL queries or Table API queries that use a processing time attribute are working.
