[TIter] don't understand a thing...

Hi,

Using the TObjNum class defined in the tcollex example ($ROOTSYS/test),
I am trying to iter over a list, and make the list bigger inside the
loop :

  TList list ;
  TObjNum* obj ;
  TIter next(&list) ;
    
  list.Add(new TObjNum(1)) ;
  list.Add(new TObjNum(2)) ;
  list.Add(new TObjNum(3)) ;
  
  while ( obj = (TObjNum*)next())
  {
    printf("%d  ",obj->GetNum()) ;
    if (obj->GetNum()==3) list.Add(new TObjNum(4)) ;
  }

This gives me :
1 2 3
i.e, it lacks the 4.

If I change obj->GetNum()==3 by obj->GetNum()==2 (or 1), it gives me :
1 2 3 4
i.e, correct.

Is this normal ?

Thanks.
