Grouper Users - Open Discussion List

[Tom Barton <>]

Sorry I wasn't able to get back to this until now. And I noticed that it
wasn't CC'd to grouper-users, which is usually a good idea since there
are some very knowledgeable grouper users and developers on that list.

Gary, do you recognize this?

DOMHelper.getDomFromResourceOnClassPath("resources/grouper/ui-permissions.xml");
The file resources/grouper/ui-permissions.xml doesn't exist at all!
