Polymorphic classes in workflow?

[Mike Pokraka]

...doubly frustrating because all the underlying technology allows it.
BTW, if you are going to try using NN on a system >620, could you let us
know if it works? It doesn't on 620 unless I do programmed bindings which
kinda defeats the point of simplification.

Although... I think it may be possible to develop some kind of generic
programmed binding to do the job across various object types. But right
now time is not a close enough friend to embark on such projects.

Cheers,
Mike
