Was able to reproduce the NPE only if the RPG has transmission enabled, testing
a fix now and will hopefully have a PR up soon.
The other issue I mentioned above is a separate issue which I will created a
different Jira for and will not be part of this fix.

Thanks for template and info, very helpful.
So far I haven't been able to reproduce the NPE (tried 1.5.0 and master), but
the steps above do produce a possible related issue for me...
After reverting the changes, it does remove the connection between the funnel
and RPG, but the PG still says it has a local modification of "Remote Input
Port was added" and if I click on the arrow for that change I get a pop-up with:
{code:java}
Unable to locate group with id '71738021-6b95-3dea-4ac9-017308d02c87'.
Unable to load the group for the specified component.{code}
The remote ports from the RPG should not be factored in during the diff.

I uploaded a template that I was able to reproduce this with.
# instantiate the template
# get it versioned in the registry
# update the RPG configuration with a nifi hostname that actually has an input
port that can accept site to site
# connect the funnel to the RPG
# start up the process group, but dont enable transmission on the RPG
# step out of the process group and attempt to revert the local changes

[jira] [Commented] (NIFI-4841) NPE when reverting local modifications to a versioned process group
[

Bryan Bende commented on NIFI-4841:

[~cemeyer2] thanks for reporting this!
Would you be able to provide the list of changes being reverted when this
happens (assuming it isn't too large of a list)?
Also, after this error happened were the local changes still present, or did it
revert them but just showed an error while it happened?
