David Eric Pugh commented on SOLR-14422:
----------------------------------------
I've been learning more Angular 1 this past year than I wanted, as part of
supporting github.com/o19s/quepid. My understanding of the purpose of ngCloak
is for this same issue, and I've fixed some similar initialization issues in
Quepid with this approach. I am headed out of town for a few days, but if
[~krisden]doesn't get a chance to look at it, ping me and I can next week.

> Key: SOLR-14422
> URL: https://issues.apache.org/jira/browse/SOLR-14422
> Project: Solr
> Issue Type: Bug
> Components: Admin UI
> Affects Versions: 8.5, 8.5.1, 8.5.2
> Reporter: Colvin Cowie
> Priority: Minor
> Attachments: SOLR-14422.patch, image-2020-04-21-14-51-18-923.png

> When loading / refreshing the Admin UI in 8.5.1, it briefly but _visibly_
> shows a placeholder for the "SolrCore Initialization Failures" error message,
> with a lot of redness. It looks like there is a real problem. Obviously the
> message then disappears, and it can be ignored.
> However, if I was a first time user, it would not give me confidence that
> everything is okay. In a way, an error message that appears briefly then
> disappears before I can finish reading it is worse than one which just stays
> there.

>
> I suspect that SOLR-14132 will have caused this
>
> From a (very) brief googling it seems like using the ng-cloak attribute is
> the right way to fix this, and it certainly seems to work for me.

> I will attach a patch with it, but if someone who actually knows Angular etc
> has a better approach then please go for it
