--------------------------------
Summary: If funnel is made both the source and destination of a
connection, connection cannot be removed
Key: NIFI-5142
URL: https://issues.apache.org/jira/browse/NIFI-5142
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
To replicate, follow these steps:
1) Add a Funnel
2) Add an Output Port
3) Connect the Funnel to the Output Port
4) Add a bend point to the Connection (to help with the next step)
5) Attempt to change the target of the Connection to the Funnel (creating a
self-loop)
6) An error is reported as expected
7) At this point, it is impossible to directly remove that Connection.
Something appears to be in a bad state.
8) However, if you attempt to remove the Funnel the framework will implicitly
removes all outgoing Connections. Possibly due to the bad state mentioned in
the previous step, the Connection is not removed and remains in the flow.xml.gz
even though the source of the Connection is removed. These leaves the
flow.xml.gz with a Connection with a missing source element.
