I just wanted to report that this worked like a treat!
The actual syntax I ended up using was:
WITH ProductSpecialist.getItem(self.id) COMPUTE
theRealThing = (RESULT is _.None) and NOT_FOUND or RESULT
WITH self.theRealThing COMPUTE
name=title, description=shortDescription, available=1
discountPrice is a method of the online catalog's original DataSkin
object, used to compute a percentage discount for 'web delivery'. My
app uses the notion of availablility. There was no such notion in the
catalog dataskins.. so I just set it to be an unconditional 'true'.
This way we didn't even to use property sheets. Basically the
skinscript could map the properties (and methods) that already existed
in the 'online catalog' onto properties of my 'virtual dataskins' so
that my app didn't need to be changed at all.
This was also nice since in my Specialist I could do things
After the user is finished working in my 'app area' they could
get redirected back to the actual object that my Specialist
was 'posing' for...
