BlackBerry Torch scrolling issue

I have created an app which is working fine on BlackBerry bold but when I installed it on Torch the screen is not scrolling.. I have used Manager with enabled vertical scrolling and added it to another master vertical field manager? Did any one get this issue before ??

the code f开发者_Go百科or the manager is below

public class TableManager extends Manager {

public int HEIGHT = 0;

public TableManager(int height) {
    super(Manager.USE_ALL_WIDTH|Manager.VERTICAL_SCROLL);
    HEIGHT = height;
}

public int getPreferredWidth() {
    return Constants.width * 90 / 100;
}

public int getPreferredHeight() {
    return HEIGHT;
}

protected void sublayout(int maxWidth, int maxHeight) {     
    int y = 150;
    try{
        int count = getFieldCount();
        for (int i = 0; i < count; i++) {
            Field field = getField(i);
            layoutChild(field, field.getPreferredWidth(), field
                    .getPreferredHeight());
            setPositionChild(field, (Constants.width - field
                    .getPreferredWidth()) >> 1, y);
            y += field.getPreferredHeight();
        }
        setExtent(maxWidth, HEIGHT);

    }catch(Exception e){
        e.printStackTrace();
    }

}

}

Try to add your TableManager to a master manager that is not vertically Scrollable.

You may also use a simple VerticalFieldManager with any Field inside set to FIELD_HCENTER instead of using this TableManager.
