Grouper Users - Open Discussion List

[Peter DiCamillo <>]

There may be a problem after all. In addition to adding an attribute, 
I'm also using the filter to remove some attributes for non-privileged 
users. However, the attributes are not removed when I used Export 
Members for a group. Maybe there's another missing call to the subject 
filter?

Export Member creates a file with all the data (too much data in this 
case), but also generates a null pointer exception in the log. It 
appears to be trying to display an error message, but failing.  I've 
attached the log data.
