Below I'm trying to set a Point output parameter. However, right after setting I check the type and it's None. See attachment for GP results. I've also tried GPPoint with no success.
Fundamentally it looks like only certain Types can be used for output parameters, but what others besides scalars are supported? Seems like a simple Point should...
