Description

Testing ListenSMTP processor. It has some bad behavior whereby it will not stop when told to. But on the UI i cannot tell that at all. So, i went to edit the processor config which I was able to do. Then went to start it and I get

7667f0c7-0156-1000-8181-5b556f8544da cannot be started because it is not stopped. Current state is STOPPING

There should be a visual indicator of its status and we should not be able to edit a processor which is not stopped.

More details on that specific case here https://issues.apache.org/jira/browse/NIFI-2519#

But key is that a bad behaving processor can allow the user to do things they should not be able to.
