[keycloak-dev] KEYCLOAK-9574 Role selection in Federation Provider Mappers broken in 4.8.3.Final

[Thomas Darimont]

Hello,

Yesterday, I noticed that the role selection is broken in federation
provider mappers, e.g. hardcoded-ldap-role-mapper.

See: https://issues.jboss.org/browse/KEYCLOAK-9574
It seems that the format how single role selections are transferred to the
server is broken.

Did the config structure change, or has this been broken for a while?
I provided a fix (html, js) via PR.

Cheers,
Thomas
