Comment 3 for bug 1420590

For testing:

1) create a groups.csv file for uploading groups via csv - eg:

shortname,displayname,roles,editroles
groupone,Group One,standard,admin
grouptwo,Group Two,standard,all

2) make sure when you upload the groups that the institution is set to 'no institution'

3) create a groupmembers.csv file for updating group members for the groups you just made - eg:

shortname,username,role
mygroupone,test01,admin
mygrouptwo,test02,admin

4) log into the site as the user, eg test01 and go and edit the group - update the description field

5) On save you should get:
