@pvillard31 Thanks for the PR! I can see what is happening here and I think
a slightly different solution is required. With the introduction of NIFI-5208
we should be watching the cluster status actively so we can track the
disconnected state. Because this state can change, I think we need to
reconsider the columns we show when the listing is opened (not when the UI is
bootstrapped). We actually have the same issue showing component state. I am
going to open up another PR with this alternate solution.
