[Building Sakai] Adding member to Site with API: "role undefined" although it exists

[Michael Mertins]

Hello,

when I try to add a new member to a site I use

site.addMember(userid, "Student", true, false);

The role "Student" exists and can be found with

site.getRoles()

(toString() gives  org.sakaiproject.authz.impl.BaseRole at f3371a1b on ID
"Student")

The site has status not joinable. Can I still add a member to it with the
API? Manually this is possible.

Is there any other reason why the user cannot be added and why I still get
this error:

2013-12-12 00:44:32,337  WARN ajp-bio-127.0.0.1-8009-exec-10
org.sakaiproject.authz.impl.BaseAuthzGroup - .addUserRole: role undefined:
"Student"

Do I need to use another Service to add the user to the role first?

Maybe someone knows...

Best wishes,


Michael
