Same Problem:
Label wrap and Scrolling the ScrollPane (http://www.badlogicgames.com/forum/viewtopic.php?f=11&t=11089&p=49905&hilit=ScrollPane#p49905)

How do I move to the last inserted Label?

I try this.scrollTo(0, 0, 0, 0);, no work corretly, See the figure below:
Note: I try too setScrollX and setScrollY but it doesn't work.

public class LogScrollPane extends ScrollPane {
   
   private static Table log = new Table();
   private final int MAX_SIZE   =   10;
   
   public LogScrollPane(Skin skin) {
      super(log, skin);
      //clear();
      this.setScrollingDisabled(false, false);
      //this.setForceScroll(false, true);
      log.align(Align.left);
   }
   
   public void add(Label label) {
     log.add(label);
      log.row();
     updateList();      
      this.scrollTo(0, 0, 0, 0);
      this.invalidate();
   }
   
   public void updateList(){
      int count = log.getChildren().size;
      int result = count-MAX_SIZE;
      if (result>0){
         for (int a=0;a<result;a++){
            log.removeActor(log.getChildren().get(a));
         }        
      }
   }
   
   public void clear() {
      log.clear();
      this.invalidate();
   }
}


Found that when the method is executed below (updateList ()), it does what it should, displaying the last added.
Note Remember that it ta displaying the penultimate added.
