 IMO, this is weakness of most formwizard/page flows in webapps on the
internet. The ability to jump around within pageflows may be needed by the
overall business reqs. In my experience developing intranet apps, there
were situations where the flow of forms couldn't be predicted or
formalized (only given a "normal"/best-case pageflow), but all the forms
had to be tied together as one functional "workflow".

I definitely agree with Vic as well about programming defensively. If
pageflows was robust enough to arbitrarily allow teh user to move about
when deemed necessary, this would be a great advantage for many users.
