API - How to set ConnectionBehavior?

[RickPalo]

Hello,
I am creating a SplineController and trying to set the Connection behavior. 

Code:

splineController.ConnectionBehavior = SplineController.ConnectionBehaviors.RandomSpline;

  I get an error that 'SplineController' does not contain a definition for 'ConnectionBehaviors', although the API documentation has it.  Is the syntax wrong?  
Thank you!
