SplineController Reset to initial Position

[aspartamed]

Thanks for the fast response 

mySplineController.Reset()   is protected.

Something to note is I am dynamically changing the location of the ControlPoints of the Spline used by the SplineController. So its possible that is part of the cause of the index out of bounds, I suspect the spline is getting shorter and that isnt handled by that code.

Is there something that should be called when the spline is changed?

Either use 

mySplineController.Reset()  

or 

mySplineController.Position=mySplineController.InitialPosition

Both should work. I'm looking into the exception, that shouldn't happen. Anyways, ResetOnStop only has an effect if you use the Animate feature.
