Android onClick event doesn't fire

Question

I really need help with this question because this is the only thing that does not work in my application. I have a list managed by an adapter extending the BaseAdapter.

The getview im function uses convertView to configure OnClickListener. This OnClickListener works well when I touch the screen, but if I use the HTC Desire trackball, I see that the line is blinking on the screen, but OnClickListener is not called ...

I read the Android developer guide: http://developer.android.com/guide/topics/ui/ui-events.html and tell him that I have to get the onClick event from the trackball ...

I put my getview code here if someone sees anything strange. If you have an idea on what I can do, let me know.

public View getView(int position, View convertView, ViewGroup parent) {
        //ici on va utiliser un mécanisme de cache avec le Tag Holder
        MyTag holder;           
        if (convertView == null){
            //On se branche sur le bon layout
            // convertView = inflater.inflate(android.R.layout.simple_list_item_2, null)
             convertView = inflater.inflate(R.layout.twolines, null);
            holder          = new MyTag();
            //on récupère les éléments du layout dans le holder
            holder.txtData  = (TextView)convertView.findViewById(R.id.productTitle);
            holder.txtExtra = (TextView)convertView.findViewById(android.R.id.text2);
            holder.imgScreenshot = (ImageView)convertView.findViewById(R.id.Screenshot);
            holder.imgFlag = (ImageView)convertView.findViewById(R.id.Flag);

            //holder.mLoginButton = (LoginButton) convertView.findViewById(R.id.login);
            holder.mPostButton = (ImageView) convertView.findViewById(R.id.postButton);

            //sauvegarde du holder
            convertView.setTag(holder);
        } else {
            holder = (MyTag)convertView.getTag();
        }


        //Facebook post button management
        holder.mPostButton.setOnClickListener((OnClickListener) new OnPostClickListener(convertView.getContext(),mFacebook, Long.toString(data[position].videoId), data[position].title, data[position].publisher, data[position].imageUrl));

        holder.mPostButton.setImageResource(com.cedemo.scan.utils.getPostButtonResId());


        //data update
        if(data[position].title != null)
            holder.txtData.setText(data[position].title);
        if(data[position].publisher != null)
            holder.txtExtra.setText(data[position].publisher);



        //get and set the language flag
        if(data[position].language != null)
            holder.imgFlag.setImageResource(com.cedemo.scan.utils.getFlag(data[position].language));

        //set the screenshot
        if(data[position].myVideoScreenshotBm != null)
            holder.imgScreenshot.setImageBitmap(data[position].myVideoScreenshotBm);


                    /* =================================================================

                       THIS FUNCTION IS NOT CALLED WHEN I CLICK ON THE TRACKBALL
                       BUT IS CALLED WHEN I TOUCH THE SCREEN.
                       WHEN I USE THE TRACKBALL THE SELECTED ROW IS FLASHING ONCE.

                       ================================================================= */
        //set the click mechanic if there is a valid video url
        if(data[position].url != null) {
            convertView.setOnClickListener((OnClickListener) new OnProductClickListener(position));


        }

        return convertView;
    }
