Grouper Users - Open Discussion List

[Tom Zeller <>]

I think the NPE is thrown because the name of the stem the groups are
being imported into is null. I suggest trying to import groups into a
Grouper stem that you create, rather than the root stem.

Importing groups into the root stem might expose a bug, I thought
there were tests for that case, but I do not remember exactly.
