[jira] [Created] (NIFI-6126) Change nf-canvas to respond to keyup events rather than keydown

             Summary: Change nf-canvas to respond to keyup events rather than keydown
                 Key: NIFI-6126
                 URL: https://issues.apache.org/jira/browse/NIFI-6126
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core UI
    Affects Versions: 1.9.0
            Reporter: Robert Fellows
            Assignee: Robert Fellows


nf-canvas responds to keydown events currently. This allows for a scenario where the user can hold down CTRL + R and continuously refresh the canvas, sending many requests to the server and potentially cause a Denial of Service.

It really should be listening for keyup instead.
