Refresh spline doesn't seem to be working

[dazz777]

hi, So I'm creating a spline and adding 2 control points, when I try to get a refernce to one of them I get a null ref exception, see code below :
The following code is run ONLY ONCE while the  left mouse button is down :

Code:

drawmousePOS_OBJ = GameObject.Find ("mousePOS");

drawmousePOS_OBJ.AddComponent<CurvySpline> ().Interpolation = CurvyInterpolation.Bezier;
drawing_spline = drawmousePOS_OBJ.GetComponent<CurvySpline> ();
drawing_spline.Add ().transform.position = v3;
drawing_spline.Add ().transform.position = v3;


drawing_spline.SetDirtyAll ();
drawing_spline.Refresh ();

drawtaxiCP0002 = GameObject.Find ("mousePOS/CP0001");
Debug.Log (drawtaxiCP0002.transform.position ); // this line creates a null ref exception

 

the spline & 2 control points are definately there.

But if i change the code so that 

Code:

drawtaxiCP0002 = GameObject.Find ("mousePOS/CP0001");

Debug.Log (drawtaxiCP0002.transform.position ); // works as expected !!

is ran  after the first time the mouse button is down it works.

It even though I'm refreshing the spline it seems like it wont refresh until update is run again.
