Resolution: Feedback Received
Apache NiFi 1.x is no longer maintained and no new release is planned on the
1.x release line. Marking as resolved as part of a cleanup operation. Please

2.x.
> ControllerServiceDefintions getting lost on dynamic properties referencing
> services
> -----------------------------------------------------------------------------------
>
> Key: NIFI-8012
> URL: https://issues.apache.org/jira/browse/NIFI-8012
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.12.1
> Reporter: Art DeCarlo
> Priority: Major
>
> When changing processor versions, controllerServiceDefintions can be
> intermittently lost for dynamic control service properties because of the
> random order that properties are looped through and set in
> AbstractComponentNode.refreshProperties().
> On a custom processor, where a static property value influences the
> PropertyDescriptor definitions of dynamic properties, the processor needs to
> set the values of the static properties before
> getSupportedDynamicPropertyDescriptor() is called.
> In my specific case, I have a custom processor similar to JoltTransformJSON,
> where the user-provided specification can trigger creation of multiple
> RecordLookupService or StringLookupService dynamic properties.
> This works well, except when doing an upgrade and changing the processor
> version. Because of the issue outlined above, the service definitions can be
> lost for the dynamic service properties. Once lost, when viewing the
> configuration of the processor, the values of the dynamic service definitions
> simply appear as the GUID identifiers of those services, and the Controller
> Services Settings tab no longer shows the processor as being a Referencing
> Component.
> Similarly, the loop in AbstractComponentNode.setProperties() should be
> updated to loop through the non-dynamic properties first, followed by the
> dynamic properties.
