Dear Axis users,
Another piece of the puzzle that I should have mentioned: dynamic proxies
work fine for me (via code much like that below) as long as none of my
return values are type-mapped. So type mapping works and dynamic proxies
work, but they don't work together (for return values) for me. Any
suggestions?
