This is a good question -- you didn't do anything wrong.  the issue
is a hard one, in that the deployed portal contains code which assumes
an older API for content objects.  If you have not modified the deployed
portal's DTML yourself (that is, any of the DTML Methods which are in
the
portal root), you can apply the fix you describe manually, and then use
the "Reconfigure Portal" action to refresh the remainder of the DTML
from
the versions stored in the product.

Sorry for any confusion.  We do need to work out better ways to manage
changes to through-the-web code/configuration, as your question points
out.
