--------------------------------------
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:

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.
