I have seen this happen sometimes (for some reason not always..) when you don't use an explicit namespace for the app...i.e. use a default namespace so if you use
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" /> you should be ok But, if you use <Application xmlns="http://www.adobe.com/2006/mxml" /> (defaults the namespace) you will see that error in design view.
