How jira agile maintains the record of the boards created by different user?

[Alok Singh]

I need to implement something similar but unable to do so as I am getting sql exception while trying to save the Application user in the table as one of the column.

Don't try to save the ApplicationUser object itself; save the application user's key as a String value.

Resolve the user later using getUserByKeyEvenWhenUnknown to guarantee that you can format the user's information properly even if they were later deleted.

Thanks a lot Chris. It worked.

If you are particularly interested in JIRA Agile implementation then you should look to sources.

For persisting data in your custom addon you should use Active Objects: https://developer.atlassian.com/docs/atlassian-platform-common-components/active-objects/
