I ran into this same problem a while back and had to resort to a workaround of comparing the incoming collection to the Selection's contents. If they're the same, nothing was selected.
I did file a bug report/feature request to change this behavior a while back, but I don't think anything has been done about it yet.

I am trying to create a command getting a collection, so I use args.AddWithHandler( L"arg", siArgHandlerCollection)), but the argument always defaults to the Softimage selection if void. So, I would like that upon running MyCommand(""), Soft would not push the selection (if any) in, but send me a void argument. Any clue? Thanks. Stefano
