No assignable roles shown

This issue is caused when saving the array of roles that can be modified.
It is saved in a format that is different from the array returned by user_role_names(TRUE);.
When loading the roles that are present on both of these arrays, none are returned, because they don't have the same format.

I've created a patch that uses the "correct" format (machine_name => Display name) to save the list of roles that can be modified when submitting the form.

It appears I've missed something.

When loading the form, the current configuration is not shown.

Changes:
- Fixed default values for the form display.
- Fixed faulty data when enabling only some roles.
- Fixed missing punctuation.

can confirm patch works

Edit: Sorry have to write again, the path is not working on Drupal 9. The roles are not saved

I found that after applying this patch, I needed to visit admin/people/roleassign and re-save the configuration. That made the roles appear, but I still could not save them. It would say "There was a problem with your form submission."

Marking this as Needs Work since several people reported issues with the latest patch.

Hi, i'll try to work on this

Since the previous patch was working for some people and not for others i created a new patch from the begging.
It appears to be working. In case of any suggestion just comment that i can improve :)

Hi!

Patch in #10 works well, +1 for this.

Here's what I did in this review:
- created "MgtCommittee" and "registered maintainer" roles;
- added users "mgtcommittee" and "joe_testing" with the roles above;
- went to /admin/people/roleassign and I selected roles "MgtCommittee" and "registered maintainer";
- added the following permissions:

Assign roles
Warning: Give to trusted roles only; this permission has security implications. Allow users with the "Administer users" permission to assign a restricted set of roles.

Administer users
Warning: Give to trusted roles only; this permission has security implications. Manage all user accounts. This includes editing all user information, changes of email addresses and passwords, issuing emails to users and blocking and deleting user accounts.

- then I logged as mgtcommittee and went to /user/3/edit.

Before:

After:

Leaving status as "Needs Review" for those who had problems before check it again.

I think it can be marked as RTBC If no one else disagrees.

I faced this issue, while testing #3297982: Automated Drupal 10 compatibility fixes

It feels that this module is not functional.

following with

Configuration

• Log in as site administrator.
• Go to the administration page for access control and grant Assign roles permission to those roles that should be able to assign roles to other users. Notice that besides the Assign roles permission, these roles also must have the Administer users permission.
• Go to the administration page for role assign and select those roles that should be available for assignment by users with Assign roles permission.
• For each user that should be able to assign roles, go to the user's account and select a role with both the Assign roles and the Administer users permissions.

Assertions in the Automated testing are not doing the right needed checks.

Thank you for the patch from #10

Although there has been some documented steps in this thread, I am having trouble reproducing this. Can someone provide some clearer steps on how to reproduce as well as what version of core you're testing on?
