[vtkusers] vtkActorCollection how this works?

Hello everybody,

I'm using the class vtkPIcker to pick an object in the scene. From the class picker I'm getting the vtkActorCollection using picker->GetActors()....
and so I use 

vtkActor *act = vtkActor::New();

act = actColl->GetNextItem();

to access the list of the actors but  the pointer I get back is NULL,  while if I use pick->GetActor (without the final S) I get the pointer to the actor.
I want to apply a transformation to the sselected actor so...what's the problem with the collection?

Kind Regards.
