I'm still learning Modelica, and have been looking at the "3D_Bouncingball3D.onb" example from the 1.7  testsuite and have two issues:

1.) loadModel(SimpleVisual)
This line wouldn't parse, so I tried "loadModel(Modelica.SimpleVisual)", and I think that works correctly.

2.) visualize(BouncingBall3D)
This results in the following error:

OMC-ERROR:
"ERROR: systemimpl.c:value_to_type_desc failed: Values.CODE

"

Could someone give me a clue as to what's gone wrong here?  All I wanted was to see the bouncing ball!
