[x3d-public] HTML slider and TimeSensor scrubbing behavior

I Andreas,
I did get Vince’s suggestion of "InterpolatorNode.setFieldValue('set_fraction', ts_fraction)” to work. I will try your suggestion as well.
Regarding your suggestion of resetting startTime after scrubbing, I assume that this might be meant to set the new fraction of the TimeSensor to the scrubbed value.
However, this does not work for me. In fact, I can see no way to set a new fraction value for the TimeSensor when playing begins after scrubbing, given it’s specification:
TimeSensor : X3DTimeDependentNode, X3DSensorNode {
SFTime [in,out] cycleInterval 1 (0,∞)
SFBool [in,out] enabled TRUE
SFBool [in,out] loop FALSE
SFNode [in,out] metadata NULL [X3DMetadataObject]
SFTime [in,out] pauseTime 0 (-∞,∞)
SFTime [in,out] resumeTime 0
SFTime [in,out] startTime 0 (-∞,∞)
SFTime [in,out] stopTime 0 (-∞,∞)
SFTime [out] cycleTime
SFTime [out] elapsedTime
SFFloat [out] fraction_changed
SFBool [out] isActive
SFBool [out] isPaused
SFTime [out] time
}
Am I missing something?
