--------------------------------
Summary: When selecting a controller service for a processor,
services that belong to the wrong scope are shown
Key: NIFI-4295
URL: https://issues.apache.org/jira/browse/NIFI-4295
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.4.0
Reporter: Mark Payne
Assignee: Mark Payne
Priority: Blocker
Fix For: 1.4.0
I have a Process Group, and in that Process Group I have defined a Controller
Service. If I then move up to the root group and add a Processor, that takes a
Controller Service of that type, I can now choose the Controller Service that
is defined in a child group. When I do so, my processor becomes invalid and the
reason given for the processor to be invalid is a NullPointer:

I believe that this issue was introduced on 'master' (1.4.0-SNAPSHOT) and has
not made it into any releases yet.
