Actually, the operator changes done in a modal PPG can and should be
reflected in the scene (try creating any primitive in immed mode).
The only difference is that the stack gets frozen, well, immediately
after you click ok or cancel.
If you want to have this behavior in your custom operator, I found that
it works well if your parameter callbacks look like this:
function OpXY_paramXY_OnChanged()
{
var operationMode =
Preferences.GetPreferenceValue("xsiprivate_unclassified.OperationMode");
if(operationMode == siImmediateOperation)
DelayedRefresh();
}

That's why i was asking whether immediate mode is activated . Usually,
modal PPGs pop up when immediate mode is turned on,
so the user cannot make additional changes while the node change is
still pending (the operation has not been completed by committing the
operator to the stack and have it automatically collapsed/frozen). If
I remember correctly, for custom ops, this must be done manually by
opening the PPG in modal mode, but I believe to remember that it
doesn't do real time updates like the factory ops do.
Oh wow, thank you so much for pointing this out! It all makes sense now.

I don't think anyone has mentioned this yet, but I think it's because
you are inspecting the PPG in siModal mode.
siModal will give you a box to say OK or Cancel, but yes, changes are
not reflected live in the scene. This is what modal means.
