             Summary: Empty Queue modal dialog blocks the UI on a new empty connection
                 Key: NIFI-1160
                 URL: https://issues.apache.org/jira/browse/NIFI-1160
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core UI
    Affects Versions: 0.4.0
            Reporter: Andrew Grande
            Priority: Minor
         Attachments: screenshot-1.png

This is reproduced when building a new flow:
* Add GenerateFlowFile
* Add AttributesToJSON
* Connect Generate -> AttributesToJSON
* Don't start anything
* Right click the connection -> Empty queue, confirm when prompted

*Expected*: either no action (stopped empty queue, 0 entries) or action performed and dialog dismissed.
*Actual*: the modal dialog shows 100%, 'Completed Successfully' message, the button says 'Stop' and there's no way to dismiss the dialog until after a complete UI reload.
