SetMax() setVisibleAmount() of Table view's scrollbar are reset

Question

Hi,
I have a table view which contains 166 rows of data. I want the table view's scroller to show only 15 rows.
Basically, I've set scroller's properties like this: setMax(166) and setVisibleAmount(15)
Unfortunately, it seems the properties previously set are later reset when displaying the table view ... Actually, I've added a listener to the scroller's value property and found out that the value's range is always between 0 and 1 and also the scroller shows more than the visible amount I had set. Normally, the value range should be between 0 and 166 and the table view should only show 15 rows. Am I right??
Basically I've created a customTableView which extends TableView and add a listener to the skin in the contructor
Here is a portion of my CustomTableView constructor, whichs
1) Get a reference of the scrollbar from the table view skin.
2) Add listener to the scroller's value property.
3) Set properties max, visibleAmount, width and height
skinProperty().addListener(new ChangeListener<Skin>()
            public void changed(ObservableValue<? extends Skin> pObservable, Skin pOldValue, Skin pNewValue)
                // get vitual flow node
          if (scbVertical == null)
                     ObservableList<Node> ovlChildren = ((SkinBase)pNewValue).getChildren();
                     Node node;
                     for (int i = 0, anz = ovlChildren.size(); i < anz && flow == null; i++)
                          node = ovlChildren.get(i);
                          if (node instanceof VirtualFlow)
                               flow = (VirtualFlow)node;
                      // get scroller reference
                     if (flow != null)
                             ovlChildren =flow.getChildrenUnmodifiable();
                             for (int i = 0, anz = ovlChildren.size(); i < anz && scbVertical == null; i++)
                              node = ovlChildren.get(i);                           
                              if (node instanceof ScrollBar && ((ScrollBar)node).getOrientation() == Orientation.VERTICAL)
                                   scbVertical = (ScrollBar)node;
                        //add listener to scroller value
                         if (scbVertical != null)
                              scbVertical.setPrefSize(width, rowHeight*rowCount);
                              scbVertical.setMaxSize(width, rowHeight*rowCount);                                                       
                              scbVertical.setVisibleAmount(rowCount); //15
                              scbVertical.setMax(getItems().size()); //166
                              scbVertical.valueProperty().addListener(new ChangeListener()
                         public void changed(ObservableValue ov, Object oldValue, Object newValue)
                              System.out.println("max:"+scbVertical.getMax() +" scroll: " + scbVertical.getValue());
    }So my question is why setMax() and setVisibleAmount() are not taken into account()???
