----------------------------------------
Summary: Controller services do not refer to any component when
they are not associated with a top-level process group
Key: NIFI-8044
URL: https://issues.apache.org/jira/browse/NIFI-8044
Project: Apache NiFi
Issue Type: Bug
Components: Flow Versioning
Affects Versions: 1.11.4
Environment: Any environment
Reporter: Samuele Lenticchia
When the controller services are defined in a scope higher than the first level
and the flow is versioned, when you import the flow, the controller services
configuration page (settings) says that it does not refer to any component.
*Scenario*
I have a process group (I will name it B) nested in a process group (that I
will name A) that is at top-level. So they will be:
NiFi Flow » A » B
In process group B, it is defined at least one controller service (scope B)
which refers to at least one component (Component_B) in this process group.
Process group A is versioned with the name FlowA.
*Issue*
When I import FlowA from the registry, the service at scope B says "No
referencing components" on the settings page. Also, if I try to enable it, the
same text "No referencing components" is shown under the "Referencing
Components" label.
*Expected behavior*
When I import FlowA, the service at scope B should list the processors and/or
controller services that refer to this service.
