title: Prevent last component of LWUIT form from losing focus when down arrow key is pressed
body: <p>I have a lwuit <code>Form</code> to which I have added a <code>Container</code>. The <code>Container</code> has a <code>TextArea</code>, some <code>RadioButtons</code> and finally another <code>Container</code> which has some <code>Buttons</code>.</p>
  
  <p>1)<code>TextArea</code><br>
  2)<code>RadioButtons</code><br>
  3)Another <code>Container</code> with some <code>Buttons</code><br></p>
  
  <p>Now if the focus is on my last <code>Container</code> on the <code>Form</code> and I press the 'down arrow key' the focus jumps to the first component <code>TextArea</code> .</p>
  
  <p>Likewise, if the focus is on my first <code>Container</code> on the <code>Form</code> <code>TextArea</code> and I press the 'up arrow key' the focus jumps to the last component of the <code>Form</code>.</p>
  
  <p>This is very annoying. How do i prevent this from happening?</p>
  
  <p>So incase the focus is on the first <code>Container</code> of the <code>Form</code> <code>TextArea</code>...I want the focus to remain on <code>TextArea</code> even if the 'up arrow' key is press.</p>
