title: ExtJS 4.2.1 - border layout with dynamic height
body: <p>i need a layout something like this:</p>
  
  <p><a href="https://fiddle.sencha.com/#fiddle/21i" rel="nofollow">https://fiddle.sencha.com/#fiddle/21i</a></p>
  
  <p>I need the west filter panel to be collapsable and my content panel has a dynamic height.</p>
  
  <p>A possibility could also be that the panel with the boarder layout has a full height and the overflow is just scrollable...</p>
  
  <p>Though i dont get a valid border layout without setting a total height to my panel.</p>
  
  <p>Please help</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>A nice workaround would be appreciated too...</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>a new fiddler with dynamic generated content</p>
