[Building Sakai] Sakai Course Management - Course Site participant list

[Mike Jennings]

We too had this same issue, as our rosters were in the course management 
tables, but the information was not being reflected correctly in the 
Section Info tool on the site.

We did the same thing as David and implemented the example batch job 
found here

https://source.sakaiproject.org/svn/edu-services/trunk/cm-service/cm-authz-synchronizer/

I did make a small addition to the code that would get every group for a 
site and do the save on that group so that the groups would be refreshed 
with the save.

>                         Collection<Group> groups = site.getGroups();
>                         // Currently there's no exposed way to refresh provided groups for a site. Instead,
>                         // it occurs as a side-effect of calling "save" on the site's associated AuthzGroup.

>                                         log.info("Trying to sync gruop id for " + group.getId());
>                                         //AuthzGroup authzGroup = authzGroupService.getAuthzGroup(group.getId());
>                                         AuthzGroup authzGroup = authzGroupService.getAuthzGroup("/site/" + site.getId() + "/group/" + group.getId());
>                                         authzGroupService.save(authzGroup);
>                                 } catch (GroupNotDefinedException e) {
>                                         log.warn("AuthzGroup for site " + site.getId() + " not found", e);
>                                         continue;
>                                 } catch (AuthzPermissionException e) {
>                                         log.warn("Unable to synchronize AuthzGroup for site " + site.getId(), e);
>                                         continue;
>                                 }
>                         }
