Nothing, it still happens from time to time. Don’t assign it to anyone, then go back to it after and assign someone, the list will populate. Just be sure not to hit the close or submit button because that acts on the merge request. Changes happen instantly.
I believe this is by design and could be improved.
The thing is that when performing an MR from your fork, you don’t have the right permissions on the upstream project, so the assign list shows only you, the owner of the fork. When you submit the MR, it is now part of the upstream project so you can assign it to the members of the repo.
Edit
So there was a similar post and as it seems this was a bug and fixed in master. Next release will have the fix included. See
thank you for your clarification. The referenced issue is from me as well.
I patched my installation (currently using 7.11.4) with the supplied patchset and it works quite fine.
