LWUIT scrolling problem

LWUIT scrolling works most of the times, however, I had problems with scrolling in a view like this:

I had some non-focusable multiline text area at the bottom of the screen and pressing down when focus is on cancel button did not scroll it.

There may be a better fix, but my quick (and dirty) fix was that, I added a focusable invisible item at the bottom !

    this.setLayout(new BoxLayout(BoxLayout.Y_AXIS));

    Component invisibleItem = createInvisibleItem();

    this.addComponent(input1);
    this.addComponent(input2);
    this.addComponent(buttonOk);
    this.addComponent(buttonCancel);

    this.addComponent(textAreaLong);
    this.addComponent(invisibleItem);
    
    buttonCancel.setNextFocusDown(invisibleItem);

   }

   private void createInvisibleItem() {
       Component component = new Container();
       component.setNextFocusDown(component); //to protect any jump
   }
