@arihantar Is the UI broken here? Have you been able to reproduce this?

@stanhu No, the UI is not broken. I did reproduce this. The above image is from my testing :). I have also checked in the console. It doesn't have any data in it. @lbot also confirmed this.

Ah, I see. I'll label this as a frontend issue unless I hear otherwise.

I don't quite understand the issue yet. The "Recipient group" seems to show some groups in the gif. But it is supposed to also list projects and users?

Has this page moved somewhere else? I can't find the "Send email to users" button or a template with "Send email notification" string/header In EE, not CE

I don't see code in the admin_email_select for users. But I did fixup the merging of results with "All", groups and projects, https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/1277

@MadLittleMods It should show us the list of available projects. As from the gif you can see, there are few projects which exist but it doesn't appear in the recipient group list.

@arihantar @DouweM how did we decide this was a recent regression, as opposed to something that had been broken for a while?

This caused some confusion in what the API endpoints should do, because they differ in master and the 8.17 stable branch, which means they now differ: https://gitlab.com/gitlab-org/gitlab-ce/issues/28853#note_24406940

That's not the fault of anyone who worked on this, but it seems from https://gitlab.com/gitlab-org/gitlab-ee/commits/master/app/assets/javascripts/admin_email_select.js that this bug is likely to have been present for a long time, which means that we probably shouldn't have picked it into the stable branch.

@smcgivern I assumed this was a recent regression because of when it was filed and the regression label it had. It was reported by a customer.

I don't think an exception was made here, we just followed the process.
