I have just downloaded and installed the nightly build of
Flex 4 SDK (Build 126.96.36.19905) 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?
