[Closed] Is getPoint in curveControl Broken?

This title says it all really, I can’t get getPoint (or setPoint) to work with a curveControl.

try(destroydialog testRoll) catch()

rollout testRoll "Test Rollout"
(
	CurveControl msa pos:[10,20] width:380 height:200 x_range:[0,1] y_range:[0,128] numCurves:1
	uiFlags:#(#drawBG, #drawgrid, #ruler, #upperToolbar, #lowerToolbar, #showReset, #constrainY, #xvalue)
	commandMode:#move_xy
)
CreateDialog testRoll width: 400

theCurve = testRoll.msa.curves[1]
insertPoint theCurve 2 (ccPoint [0.5,64] [0,0] [0,0])
zoom testRoll.msa #all
getPoint theCurve 2

Code above thows an error message:No getPoint function for ccCurve.
Am I doing something wrong?

Thanks.
