             Summary: Versioned Flows show as dirty when component versions change
                 Key: NIFI-4763
                 URL: https://issues.apache.org/jira/browse/NIFI-4763
             Project: Apache NiFi
          Issue Type: Improvement
    Affects Versions: 1.5.0
            Reporter: Bryan Bende
            Priority: Minor


While testing the 1.5.0 RC I happened to have an existing NiFi instance that was running the 1.5.0-SNAPSHOT version of the flow versioning PR, and had a bunch of example versioned flows. I upgraded this instance by replacing the lib directory with everything from the 1.5.0 RC.

When I went to the UI I noticed all the versioned PGs were showing local changes. Looking at one of them it was because the local flow had upgraded all the component versions to 1.5.0, but the last version of that flow in the registry had the components at 1.5.0-SNAPSHOT.

At this point you can try to rollback the local changes, but it can't really rollback because there are no more processors for 1.5.0-SNAPSHOT. You can save a new version of the flow with the new component versions and all is good.

This won't really be an issue until the next release when folks have already been using 1.5.0 + registry for a while and upgrade to 1.6.0 (or whatever the next release is). We may want to ignore component version differences until sometime in the future when we have an extension registry.
