Blackberry: VerticalFieldManager Child Element Not Receiving Focus

I have a VerticalFieldManger which is used as container to display a custom news feed. The idea is an image (BitmapField) and a title (LabelField) are placed in the VerticalFieldManager.

I have subclassed VerticalFieldManager for some simple custom elements and their behviours, but I have not overridden any methods declared in the VerticalFieldManager.

I would like the BitmapField to respond to touch events and navigation clicks to as to open a web browser to display a desired web page. The issue is that the VerticalFieldManager does not receive focus (I did not expect it to), nor do any of the child elements receive focus.

I have not subclassed BitmapField nor LabelField

Constructor for my subclassed VerticalFieldManager:

public NewsManagerView( boolean _isClickable, long _style ) {
    super( _style );

    this.setIsClickable( _isClickable );    // s开发者_StackOverflowets flag if this should respond to click events

    this.init();    // initialize ivars

    this.add( this.getTitle() );    // add child fields
    this.add( this.getImgFld() );
    this.add( this.getUrl() );
}

Which gets instantiated like this:

this.setNewsManager( new NewsManagerView(this.getIsConnected(), Field.USE_ALL_WIDTH) );

This is a known problem. I started a topic in BB support forum http://supportforums.blackberry.com/t5/Java-Development/Scroll-happening-but-Vertical-Field-Manager-Not-Moving/m-p/1214481

And the answer given was http://supportforums.blackberry.com/t5/Java-Development/My-scrollable-manager-is-not-scrolling/ta-p/445247

Sorry that is not a real answer but is the only workaround that's available for the moment

EDIT: In the BB forum a new post added says:

A friend gave me the solution... you can put your manager into an horizontal manager and then you can just add an nullfield with a focusable behaviour, This will do the trick

You can try that.

VerticalFieldManager datavfm=new VerticalFieldManager(FOCUSABLE)
{
    protected void paintBackground(Graphics graphics) 
    {
        if(!isFocus())
        {
            graphics.setColor( 0xDDDDDD );
            graphics.fillRoundRect( 0, 0, 318, 30, 18, 18);
            graphics.setColor( 0x000000 );
            graphics.drawRoundRect( 0, 0, 318, 30, 18, 18);
            invalidate();
        }
        else
        {
            graphics.setColor( 0x005DE7 );
            graphics.fillRoundRect( 0, 0, 318, 30, 18, 18);
            graphics.setColor( 0xFFFFFF );
            graphics.drawRoundRect( 0, 0, 318, 30, 18, 18);
            graphics.setColor( 0xFFFFFF );
            invalidate();
        }
    }
    protected void sublayout(int maxWidth,int maxHeight)
    {
        super.sublayout(318, 30);
        super.setExtent(318, 30);
    }
    protected boolean navigationClick(int status,int time)
    {
        GetPNRStatus(strPNRNumber);
        return true;
    }
    protected boolean keyChar(char c, int status, int time)
    {
        if (c == Characters.ENTER)
        {
            GetPNRStatus(strPNRNumber);
        }
        return true;
    }
};
