[vtkusers] ImageActor problem...and actorCollection

[Giancarlo Amati]

Good morning,

I have three ImageActor objects that have been added to the pipeline using the standard

renderer->AddActor(imgAct);

now the number of actor visible has been increased but unfortunately whenever I call the GetActors() the ActorCollection that is returned is empty.
Does anybody know WHY?

Kind Regards.
Giancarlo
