CS3 JS Add group into frame

Question

Hi
In InDesign UI you can copy a group of frames and paste it into another frame.
I'm trying to replicate the results via JS
I tried this:
x = app.activeDocument.rectangles.add();
y = app.activeDocument.ovals.add();
z = app.activeDocument.ovals.add();
x.groups.add([y,z]);
then this:
x = app.activeDocument.rectangles.add();
x.groups.add([app.activeDocument.ovals.add(),app.activeDocument.ovals.add()]);
Both attempts ended up with "Invalid parameter" error message
Then I tried this:
x = app.activeDocument.rectangles.add();
y = app.activeDocument.ovals.add();
z = app.activeDocument.ovals.add();
g = app.activeDocument.groups.add([y,z]);
g.select();
app.cut();
x.select();
app.pasteInto();
It did the job without errors, but I'm affraid it will be unnecessary slow in real world deployment.
Please, can anyone explain what I did wrong with my first two attempts?
Thanks for help

Hi
Having carried out more experiments I made this discovery:
(assuming that "myObject is a rectangle")
after running:
myObject.rectangles.add();
myObject.rectangles.add();
myObject.rectangles.add();
I ended up with a couple of rectangles inside of the "myObject" frame.
But they were not grouped.
Though this partly solves my problem, I'm aware that Indesign won't allow me to do this in UI. (That is, it's only a single object or a group that can be "pasted into"). Am I really in for a big problem if I use this method?
