WF ProgramExists

[Mike Pokraka]

Rick,

Just a general comment which may not apply, but I find that I tend to do
role resolution separately more often than not as it avoids most of these
conundrums.
To accomplish your scenario I'd use two conditional texts in my work item
and pass in a flag to display one or the other. It may be possible to
catch the forwarding action via a work item exit (not sure & no time to
look into it) and change the flag in the container - the new text would be
displayed automatically for the new user.

Cheers,
Mike
