Steps to reproduce:
1. Activate the custom role pattern in file custom.properties
Optional custom roles pattern (regular expression). Roles matching this pattern can be added to ACLs.
2. Try to add a role with this pattern in the series/events/template ACLs
As soon as the pattern does not follow a local defined role it is greyed out and the message "no role found" is shown
Accept the role if the role match the pattern and allow to add it to the ACLs
Workaround (if any):
