Grouper Users - Open Discussion List

[Tom Zeller <>]

Ugh, a bug. The NPE occurs on

 attribute.getValues().addAll(subject.getAttributeValues(attr.getId()));

where subject.getAttributeValues("name") returns null.

If you replace id="name" in :

<resolver:AttributeDefinition id="hasMember" xsi:type="grouper:Subject"
sourceAttributeID="viewers">
  <resolver:Dependency ref="GroupDataConnector" />
  <grouper:Attribute id="name" source="ESUP_ldap" />
</resolver:AttributeDefinition>

with anything besides "id", "name", or "description" you shouldn't
receive an exception.

I can fix this in the branch that will become 1.6.4 and send you a
patched jar - what do you think ?

P.S. May I lament how subject.getName() and
subject.getAttributeValues("name") should return the same thing ?
