> Key: NIFI-1313
> URL: https://issues.apache.org/jira/browse/NIFI-1313
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core UI
> Affects Versions: 0.4.0, 0.3.0
> Reporter: Richard Miskin
> Priority: Minor
> Attachments: example.xml
>
>
> Attempting to delete a ProcessGroup that contains another ProcessGroup, with
> a connected InputPort, triggers the message
> "Cannot delete Process Group because Input Port XXX has at least one incoming
> connection from a component outside of the Process Group. Delete this
> connection first."
> The manual solution for this is to go into the ProcessGroup, delete the
> contents and then delete the outer ProcessGroup.
> The equivalent happens for OutputPorts.
