-----------------------------------
Summary: Cannot stop Process Group using the UI controls without
"modify the component" policy access (even with "operate the component" granted)
Key: NIFI-8318
URL: https://issues.apache.org/jira/browse/NIFI-8318
Project: Apache NiFi
Issue Type: Bug
Reporter: Chris Sampson
Attachments: can_operate.png, cannot_operate.png
Given a Process Group present on the NiFi UI canvas and a user that has
"operate the component" access granted for the canvas but *not* "modify the
component" access, the "Stop"/Start" operation controls are disabled in the UI
if the user clicks on the Process Group: !cannot_operate.png!
If, however, the user clicks off the Process Group, the controls become active
again: !can_operate.png!
Right-clicking the Process Group allows for the "Stop" operation to be selected
from the menu; navigating into the Process Group and *not* selecting any
components on the canvas allows for "Stop" to be selected from the main UI
control panel.
This is confusing - if the user has "operate" permission for a component, they
surely should be able to Stop it via the main control panel (I agree that
disable/enable controls should be unavailable as that would be a component
modification, but start/stop is an operation).
