Face clicking returning copies ?

I confirm that when you click a face on the screen the TopoDS_Face returned by the function ViewerTest::PickShape() is not the original one but a copy as shown in the code below :

//=======================================================================
//function : SelectedShape
//purpose :
//=======================================================================

TopoDS_Shape AIS_InteractiveContext::SelectedShape() const
{
if (!HasOpenedContext())
{
TopoDS_Shape aResShape;
Handle(AIS_Shape) aShape = Handle(AIS_Shape)::DownCast (SelectedInteractive());
if (!aShape.IsNull())
{
aResShape = aShape->Shape().Located (TopLoc_Location (SelectedInteractive()->Transformation()) * aShape->Shape().Location());
}

return aResShape;
}
else
{
return myLocalContexts (myCurLocalIndex)->SelectedShape();
}
}

This is due to the fact that the function Located() builds a copy of the TopoDS_Shape.
The question is : how to return the original shape ? Because I woudn't want to modify the function above...
