-------------------------------------

             Summary: DataStream API PojoFieldAccessor doesn't support nested POJOs
                 Key: FLINK-3702
                 URL: https://issues.apache.org/jira/browse/FLINK-3702
             Project: Flink
          Issue Type: Bug
          Components: DataStream API
    Affects Versions: 1.0.0
            Reporter: Robert Metzger


The {{PojoFieldAccessor}} (which is used by {{.sum(String)}} and similar methods) doesn't support nested POJOs right now.

As part of FLINK-3697 I'll add a check for a nested POJO and fail with an exception.
