Brendan,
While the Next, Prev mechanism keeps the # of rows displayed and the First
Row number in PageSessionObjects, the dynamic criteria are kept in
UserSessionObjects. Not sure if it is a wise idea. If the primary concern
was built-in support for Next,Prev stuff then PageSession would have been a
better place for them. This way the DynamicCriteria affect other pages using
the same DataObject. I can't imagine it being a useful feature.
I confirmed the fact that they are stored in USO by making ND spit out the
contents of the UserSession.
