Assignee field does not autofill for certain users

[Nari Man]

I have added a few new users into JIRA and none of the new users shows in the assignee field and does not autfill.

If I type their whole name in the assignee field it is accepted but no auto fill when I start typing their name and if I drop the assignee list down and scroll, I do not see their name.

This problem is only with some new users I recently added.

Any idea?

thanks

Are you sure the newly added users are part of the right group which has permissions to "Work on Issues" and actually be put as assignee?

I had not added them to JIRA-developers group. Now it works.

Did you update that project's permission scheme to give those new users permission to be assigned issues? Or have you added those users to a group that already has the assignable user permission?
