How to access Isopoint Cluster

Hi,
I'm looking for away to get the SubcurveIndex/UValue data out again that an Isopoint Cluster was created from. 


var oObject = CreatePrim("Text", "NurbsCurve", null, null);
SelectObj("text.isopnt[(3,0.922)]", null, null);
AddToSelection("text.isopnt[(2,0.433)]", null, null);
AddToSelection("text.isopnt[(0,0.267)]", null, null);
AddToSelection("text.isopnt[(6,0.748)]", null, null);
AddToSelection("text.isopnt[(4,0.463)]", null, null);

var oCluster = 
oObject.ActivePrimitive.Geometry.AddCluster(siIsoPointCluster, 
"Isopoint_AUTO");

cElements = oCluster.Elements;
for(var i = 0; i < cElements.Count; i++)
    LogMessage(cElements(i)); // 0,1,2,3,4

var oSubComponent = oCluster.CreateSubComponent();

LogMessage("oSubComponent.Type: " + oSubComponent.Type); // 
isopntSubComponent
LogMessage("ClassName(oSubComponent): " + ClassName(oSubComponent)); // 
SubComponent


var aElements = oSubComponent.ElementArray;
LogMessage("oSubComponent.ElementArray: " + aElements); //

LogMessage("oSubComponent.ElementArray.length: " + aElements.length); // 
undefined





So neither "Cluster.Elements" nor "Cluster.CreateSubComponent()" deliver 
anything usable. Dead end?

What I'd like to achieve is to feed Isopoints into a Curve Operator.
Thanks!
Best,
Eugen
