When opening

Configuration => Subsystems => Configuration => Security (Elytron) => Security Realms => JDBC Realm => Principal Query

the field "Attribute Mapping" shows only the first attribute

via cli this looks correct

/subsystem=elytron/jdbc-realm=MySqlJDBCRealm:read-resource

{

    "outcome" => "success",

    "result" => {"principal-query" => [{

        "sql" => "SELECT u.password, r.role FROM users u, roles r WHERE u.userna

me =? AND u.username = r.username",

        "data-source" => "MySQLTestDS",

        "attribute-mapping" => [{

            "to" => "groups",

            "index" => 2

        }],

        "clear-password-mapper" => {"password-index" => 1}

    }]}

}
