Robert Fellows reopened NIFI-6253:
----------------------------------
The original fix has a regression. Re-opening to fix it.
The issue manifests in an error/warning dialog to the user when they
add/edit/delete a policy.
This happens on a call to the nfCanvasUtils.reload method. That method no
longer expects an object parameter that it is invocation sends it. It only
accepts an optional numeric value for the process group id to reload.
> UI - Process Group ID display in "Operate" palette can get out of sync when
> process groups are removed from different sessions.

> 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: 1h 10m
> 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.
