    Proper namespace in root application tag Flashbuilder 4


      In my Upgrade application to FB 4.

        if I want to just support the existing halo mx namespace in my components what do I need to do?


      If I use the following

      <mx:Application xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:local="*"



      I get unable to resolve MXML language version. Please specify language namespace on the root document tag


      ------------------------------------------------------------------------------------------ ---------------------

      However if I keep <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"




      When I revert back to above and go over any of my the mx controls with cntrl space nothing shows

      and one of my shared components also tells me the style "borderThickness" is only supported with the

      theme "halo"

      ------------------------------------------------------------------------------------------ ----------------------

      Any ideas?

      Thanks, Mike
