- Create a group with a slash in the ID, e.g. AOG-BMA/FLL
- Add a user to the group
- Add a tenant to the group
- Visit the tenants and users page of the group
- Both pages claim that the group has no users or tenants
- The user and tenant are visible in admin
- After checking the h2 query log it seems that the slash is encoded before it is send to the database. The value AOG-BMA%2FFLL is used as query parameter.
