Update of /cvs-repository/Zope3/src/zope/app/browser/container
In directory cvs.zope.org:/tmp/cvs-serv6845

	adding.py 
Log Message:
Changed to raise a user error when the user neglected to pick a
type. This is an improvement over the previous behavior. It would be
better to redisplay the form with the message.
