Updating flex builder sdk
So grab the Black Berry Play Book Simulator 2 for your operating system and start the installation process.
I used the default options and after the installation finished on my Mac, I got a new ISO file inside of my user folder: Black Berry Play Book Simulator-0.9.2
We recommend all users of Flex SDK 3.3 and earlier versions update to the newest version, Flex SDK 3.4.It includes a signed version of the Flex framework RSLs (required to use RSL caching). When I change this to use 3.3.0 or 3.4.0 I get this error message for my MXML components : "This component is based on Canvas, which is not a visual component.If you want to use a stable, tested release, download a milestone release build.A milestone release build has been declared a major release by the development team.
