--------------------------------------

             Summary: Broker diagram is not properly updated when new nodes become available
                 Key: ARTEMIS-4183
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-4183
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Web Console
    Affects Versions: 2.28.0
            Reporter: Erwin Dondorp
         Attachments: image-2023-02-26-16-36-25-761.png

Using an auto discovery cluster.
When the number of nodes is reduced, the broker diagram is properly updated when the Refresh button is used.
When the number of nodes is enlarged, the broker diagram is _not_ properly updated when the Refresh button is used. The new nodes are visible, but their cluster-connections are not shown. The diagram can easily be fixed by using the browser refresh button instead, or by temporarily switching tabs within the Artemis console.

The following diagram shows the effect:
!image-2023-02-26-16-36-25-761.png! 
left image: initial situation with 5 nodes
middle image: 3 nodes are added, and after Refresh button is used
right image: after page refresh

I know the JS code from the Console fairly well. I suspect a synchronisation error between the variables `relations` and `hiddenRelations`. I'll investigate and try to add a PR.
