But I think it is still not so simple.

May happens that SOMETIMES you must delete.

For example, you MUST delete mShownSet if you DID NOT send it to Sort.

I think you need do something as:


     selection = obj.GetMeShownSet()
                { 
                    tmp = mShownSet;
                    mShownSet = NULL;
                    return tmp;
                }  


You must call this when you going send selection to Sort().
So your second object already NOT point to this selection.

After sort you assign new selection.
