Github user 1ambda commented on the issue: https://github.com/apache/zeppelin/pull/1982 @Leemoonsoo Thanks for review. - Then we need to close the configuration panel after saving. I will update it. - You have to use echo spell provided by zeppelin (`examples/`). Published echo spell doesn't have repeat implementation since spell config feature is not merged. (https://github.com/1ambda/zeppelin-echo-spell/blob/master/index.js) - Regarding to version, I will check again.
--- If your project is set up for it, you can reply to this email and have your reply appear on GitHub as well. If your project does not have this feature enabled and wishes so, or if the feature is enabled but not working, please contact infrastructure at infrastruct...@apache.org or file a JIRA ticket with INFRA. ---
