Comment (by Karen Tracey <[EMAIL PROTECTED]>):

 Yes, the issue is whether the Admin puts a link in the column header that
 allows you to sort by the associated field.  As mentioned in the list
 discussion, the restriction has been there since initial import of the
 code into the current repository.  I assume the Admin didn't allow it
 because the ORM code didn't used to support it.  Now it does, I think the
 Admin restriction can be removed as well.  Also mentioned at the tail end
 of that list discussion is that different DBs may put null values in
 different places (either first or last), so behavior may not be entirely
 consistent from DB to DB, but I don't see that as a showstopper for
 allowing sorting by these fields.
