tySpline and emitter motion

[tycera]

I have an irregular spline that an object path follows. I'd like to use tyFlow to add a single tapering trail to the object with tySpline, but the object motionis not passed on to tySpline, even if I check "Inherit Emitter Movement" in the Position operator.

How do I get tySpline to recognise and follow the emitter motion?
