Face selection problem in NX11 Nxopen

I think trying to cast the selection response to face in this line causes the problem. It should be selection response and the response by reference it will be planar face.

Dim resp As Face = ui.SelectionManager.SelectObject(message, title, scope, selAction, includeFeatures, keepHighlighted, selectionMask_array, cursor)

I didn't tested since I don't have NX 11, Hope this works
