Problems with spline prefab

[topquarkone]

Hi,

I created a simple spline (in editor), and wrote some scripts to access it. They worked fine. I then copied that spline into assets, as a prefab.

I wrote code to instantiate the prefab, which it did! However, while it looks fine in the Editor, the script says it has Length=0, and I get a Curvy exception when I try TFToDistance or Interpolate.

Any help would be appreciated!

Thanks.

PS - 

I just tried it again. I am doing this all in Edit mode.
I am instantiating the spline in the script using 

Code:

CurvySpline mySpline = PrefabUtility.InstantiatePrefab(splinePrefab) as CurvySpline;

This *does* instantiate the spline. When I check mySpline in the code right after, and while it is indeed a spline (has the correct number of control points), it does not work as said above. If I exit the code, and come back and check it in the code, it is fine.
