Grouper Users - Open Discussion List

[Peter DiCamillo <>]

I'm having a problem with this. The relevant part of my code is:

> GrouperSession session = GrouperSession.startRootSession();
> Group group = GroupFinder.findByName(session, groupName);
> Set<Member> groupMembers = group.getImmediateMembers(null,
>                            
> GrouperUtil.toSet(SourceManager.getInstance().getSource("g:gsa")),
>                            null);

The call to GroupFinder definitely works. I'm getting this error for the 
getImmediateMembers call:

> Exception in thread "main" java.lang.NullPointerException
>         at 
> edu.internet2.middleware.grouper.privs.PrivilegeHelper.canViewMembers(PrivilegeHelper.java:522)
>         at 
> edu.internet2.middleware.grouper.MemberFinder.internal_findMembersByType(MemberFinder.java:148)
>         at 
> edu.internet2.middleware.grouper.Group.getImmediateMembers(Group.java:2952)
>         at GroupDef.showDef(GroupDef.java:101)
>         at GroupDef.main(GroupDef.java:61)

Any ideas?
