Matt Gilman updated NIFI-45:
----------------------------
Attachment: 0001-NIFI-45.patch
In order to trigger the case when reviewing, the referenced controller service
will need to be made invalid after it has been enabled. This is because a
different validation result is generated when referenced controller services
are disabled.
As the description describes without the patch, the error message is confusion.
With the patch applied, the error message includes additional context about the
validation error which helps clarify the underlying issue.

> We have a Processor that references a Controller Service (A), and A then
> references another Controller Service (B). The property value in A had a typo
> that caused it to reference an invalid service identifier. The error message
> read something along the lines of:
> 'XX' validated against 'YY' is invalid because: Controller Service is not
> valid. No controller service exists with this ID
> This looks like 'YY' (referencing Controller Service A) was an invalid
> identifier, but in reality Controller Service A was referencing an invalid
> identifier.
> Proposed fix: PropertyDescriptor, when validating a Controller Service and
> determining Controller Service is invalid should provide as its explanation
> "Controller Service is not valid: " + result
> instead of
> "Controller Service is not valid: " + result.getExplanation()
