-------------------------------------
Summary: Resolve ancestor controller service references during
Connector component verification
Key: NIFI-16338
URL: https://issues.apache.org/jira/browse/NIFI-16338
Project: Apache NiFi
Issue Type: Improvement
Reporter: Pierre Villard
Assignee: Pierre Villard
Connector component verification creates temporary contexts from versioned
component properties. During this process, StandardComponentContextProvider
translates versioned controller service identifiers to runtime instance
identifiers.
The current implementation builds this mapping using
ProcessGroup.findAllControllerServices(), which searches the current process
group and its descendants. This does not match controller service visibility
rules: a processor or controller service can reference services in its current
process group or ancestor groups, but not descendant groups.
As a result, Connector verification can fail when a component in a nested
process group references a controller service defined in a parent group. The
versioned identifier remains unresolved and validation reports that it is not a
valid controller service identifier.
