title: Navigation issue in Flex - ViewStack, states or something else?
body: <p>I have a bit of doubt regarding my application which is being created using Mate framework. The first thing user has to do is to log in, so I created Login.mxml view. After a successful login I need to display the main view with applicationControlBar at the top and a workspace below. At the moment I have two separate views, so if I understand correctly it makes sense using ViewStack.</p>
  
  <p>Thing is, I'd like also to display some kind of panel with buttons on top of the workspace after login - <a href="http://img207.imageshack.us/img207/3808/screentoi.png" rel="nofollow noreferrer">here</a> is screenshot. After clicking on a button the panel should dissapear. To complicate things a little bit more, there is a possibility for this panel to change state. Clicking on a specific button may result in showing progress bar at the bottom of panel. </p>
  
  <p>I feel I should create separate view, MenuDialog.mxml and put there buttons, progress bar and states, but how to display it on the top of the workspace? I hope my problem is clear enough :)</p>
