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

             Summary: NullPointerException when run notebook previously generated before ZEPPELIN-387
                 Key: ZEPPELIN-475
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-475
             Project: Zeppelin
          Issue Type: Bug
            Reporter: Lee moon soo
            Assignee: Lee moon soo


ZEPPELIN-387 introduces a new field "enabled" in paragraph config.
This value is persisted into note.json.

However, note.json that exists before ZEPPELIN-387 does not have "enabled" field and that cause NullPointerException
