Description
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:
