title: AvalonDock 2.0 with Prism 4 Region Adapter
body: <p>I have been playing around with this question.</p>
  
  <p><a href="https://stackoverflow.com/questions/10905238/avalondock-with-prism-region-adapter">AvalonDock with Prism Region Adapter</a></p>
  
  <p>Where someone is trying to add a prism region adapter. It sort of works but as soon as i float the panel the content vanishes and goes completely black. </p>
  
  <p>Is this an error from me?
  I have also tried using regions directly under the dockingmanager and they can be updated but not when the region is already floated. Is this expected behaviour? ie. Can a floated region be updated? </p>
  
  <p>I also tried the variation from vaccano here: <a href="http://avalondock.codeplex.com/discussions/358632" rel="nofollow noreferrer">http://avalondock.codeplex.com/discussions/358632</a></p>
  
  <p>But i don't see how the regionmanager.setregionname() method creates a region which can be updated. ie. it is nowhere to be found in my region collection.</p>
  
  <p>Any help with any or all of these much appreciated.</p>
