[patte]

Bug Report

Steps to Reproduce

• goto user page
• check a role that is unchecked
  

Actual Results

• the checkbox is checked
• but the role is not present on the user

Expected Results

• the user has the role

Environment

• OS: Ubuntu 18.10
• Browser: Chromium 66

Investigations done

In the Devtools -> Network, I see that first the addUserToRole mutation is fired as expected, but immediately afterwards removeUserFromRole mutation is executed.

Obviously only reproducible in Chromium 66 under Ubuntu

Tested and worked in:

• Chrome 67
• Firefox 61
• Safari 11

Mac OSX 10.13.5

Wontfix as long as only Chromium is affected.

Can reproduce. Maybe a backend issue at this point e.g. array missing in users attribute. Removed wontfix flag.
