--------------------------------
Summary: When changing flow version, can silently fail to update
connections connected to Output Ports
Key: NIFI-8261
URL: https://issues.apache.org/jira/browse/NIFI-8261
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
If I try to change the version of a dataflow from Version 1 to Version 2, and
the changes result in a connection being removed or its destination changing,
all is OK If the destination is not an Output Port. However if the destination
of the connection in the current version is an Output Port, and the Output Port
is running, the connection will not be updated. The logs will show no errors,
and the UI will either indicate that the connection couldn't be updated because
the destination is running, or it will claim that the update was successful
(depending on the situation). But in either case, the flow will not have been
updated properly.
