I came up with another approach....I wrote a custom tag that bridges the
sessions, specifying the attribute that I want pushed from one session
to the other. Again, I don't like this solution, but it prevents me
from having to change the displaytag-portlet code. Might it be
worthwhile to include such a tag in the displaytag-portlet project?
