spring-sesion's session objects are not mutable by default for performance reasons, see https://github.com/spring-projects/spring-session/issues/177

If you want to make them mutable you can either the grails 3 spring-session plugin wich has this as a config option https://github.com/jeetmp3/spring-session

Or

Implement your own session synchronizer (this is the approach I take, and only update if the flash object has changed) - you can find an example from the same plugin mentioned above https://github.com/jeetmp3/spring-session/blob/master/src/main/java/org/grails/plugins/springsession/web/http/HttpSessionSynchronizer.java

Stack overflow or slack are probably better places to ask these types of questions.

Thanks for your reply. So if I want to do redis session replication in grails, what is the best option there?

When using https://github.com/jeetmp3/spring-session it works, thanks @erichelgeson for helping out!
