title: Blackberry - get checked items from list with checkboxes
body: <p>How can all  checked items from a list can be fetched?</p>
  
  <p>I need to get all selected (checked) items from the list and populate a vector.</p>
  
  <p>I am not getting all selected items, I am getting only the item on which current focus is.</p>
  
  <p>I am implementing listfield with checkboxes as per the knowledgebase article.</p>
  
  <p>If I use getSelection(), it is returning me the currently highlighted list row index, and not all that have been checked.</p>
