Grouper Users - Open Discussion List

[Chris Hyzer <>]

This seems like a useful function, I added a jira request (not sure what 
release it will be in).

https://bugs.internet2.edu/jira/browse/GRP-187

I had thought if a group were a composite member of another group that you 
cant delete the group that is a member (due to foreign key... what should 
happen to the composite group?  Should the composite membership disappear?

Anyways, having said that, I couldn’t immediately reproduce, and I was able 
to run Tom Zeller's script in GSH (in grouper 1.4):

addRootStem("a", "a");
addGroup("a", "groupA", "groupA");
addStem("a", "b", "b");
addGroup("a:b", "groupB", "groupB");
addStem("a", "c", "c");
addGroup("a:b", "groupB1", "groupB1");
addGroup("a:c", "groupC1", "groupC1");
addGroup("a:c", "groupC2", "groupC2");

grouperSession = GrouperSession.startRootSession();

stem = StemFinder.findByName(grouperSession, "a");
for(child : stem.getChildGroups(Stem.Scope.SUB)) { child.delete(); }
for(childStem : stem.getChildStems(Stem.Scope.SUB)) { childStem.delete(); }
stem.delete();

StemFinder.findByName(grouperSession, "a");
//cant find!
