David,
Thank you very much for the reply and suggestions! You answered some questions
I had.
My example code uses the MethodContext constructor that initializes it to
service mode. After the simple method is run, I copy the MethodContext
environment to the screen context - so the results of the method call can be
used. Is that the right approach?
Isn't the screen widget rendering wrapped in a transaction already?

I would be fine with that enhancement. There are caveats to using the
simple-method this way (like transaction control, etc), but it
certainly works and has been done in other places. It should also be
noted that these should only be used for reading information, not for
persisting it (just like any other screen action), and that is good as
it makes the transaction and other caveats with using the simple-
methods less of an issue.
To clarify: this would be running the simple-method in "service" mode
(as opposed to request event mode) and would use the current screen
context (with a push to isolate the context) for the input context of
the simple-method. There wouldn't be any parameters per-se, but it
might be nice to put the entire context in the a "parameters" Map to
make these simple-methods more like the ones that are actually called
through the service engine. For picking out the results after the call
to the simple-method using the results Map is probably still the best
way to go, again to make it more similar to the typical coding of a
simple-method called from a service and to better isolate the context.
