I guess that you maybe do not update rolesFromRoleGroup explicitely, so it always keeps its initial state. One way to it right is to add a e.g. @Observer("rolesFromRoleGroupChange") to the listRolesFromRoleGroup() method, and to fire Events.instance().raiseEvents("rolesFromRoleGroupChange") every time you delete, add or update a role entity.
