> -------------------------------------------------------------------------------------------------------------------------------
>
> Key: NIFI-6253
> URL: https://issues.apache.org/jira/browse/NIFI-6253
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core UI
> Affects Versions: 1.9.2
> Reporter: Robert Fellows
> Assignee: Robert Fellows
> Priority: Major
> Fix For: 1.10.0
>
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> To reproduce this issue:
> # Open Nifi in 2 different browser tabs
> # Add two process groups to the canvas in one tab, then refresh the other tab
> to get the updates.
> # Take note of the Process Group IDs displayed in the "Operate" palette when
> selecting each one in the canvas.
> # Take note of the Process Group ID for the entire Flow displayed in the
> "Operate" palette (clicking on a blank spot on the canvas will update the
> palette)
> # In one of the browser tabs, delete one of the process groups.
> # Quickly switch to the other browser tab and double click on the process
> group you deleted in the other tab to attempt to enter that process group.
> # You should see a dialog indicating something to the effect of this process
> group is not able to be located (this is expected)
> # Now click on a blank spot on the canvas. Notice that the process group id
> displayed for the Flow is id for the process group that was deleted and NOT
> for the flow.
> # Expected: Clicking on the canvas should update the process group id in the
> "Operate" palette to the proper id following the failure to enter a process
> group.
