    FB3 - Flex 4 (Gumbo) SDK - Design View Problem


      I have just downloaded and installed the nightly build of Flex 4 SDK (Build for use with my Flex Builder 3.0.194161. When I create the simplest of flex applications as shown below and set the Flex compiler to use the Flex 4 SDK. When I try to switch to design view I get the following error:

      ' This component is based on Application, which is not a visual component. Switch to source mode to edit it. '

      If i change the flex comiler settings to use Flex 3 SDK it works fine. I would like to start developing for the Flex 4 SDK. Does anyone know of a solution to this problem?
