Bryan Bende commented on NIFI-7405: ----------------------------------- Thanks for reporting this. I've been unable to reproduce the error using the original steps described in NIFI-6985 and latest master. Can you provide specific steps to produce the problem? Also, is there a stacktrace in nifi-app.log or nifi-user.log that goes with the error message? > Unable to manage flows containing versioned process groups with parameter > context > ---------------------------------------------------------------------------------- > > Key: NIFI-7405 > URL: https://issues.apache.org/jira/browse/NIFI-7405 > Project: Apache NiFi > Issue Type: Bug > Components: Flow Versioning > Affects Versions: 1.11.4 > Environment: Centos 7 > Reporter: David Grootwassink > Priority: Major > > Reopen of NIFI-6985. > > When a process group that contains parameters in sub process groups is > committed.
