I get the error
VerifyError: Error #1014: Class spark.skins::SparkSkin could not be found.
and have read that you have to use merged into code not the rsl . Any idea when this will be fixed?
It's been fixed for while. The bug was in Flash Builder so that's what you will need to upgrade.
Thanks for that. By upgrade to you mean the nightly builds or is there a Flash Player upgrade elsewhere?
Sorry, my bad. There doesn't seem to be a version Flash Builder 4 newer than Beta 2 available for download.
The problem has to do with FB copying the spark RSL from the Flex SDK to the debug and/or release directories. The sparkSkins RSL ends up being copied instead of the spark RSL. There are a couple of ways to work around the problem.
1. For debug and release builds, remove spark.swc and sparkskins.swc from using framework linkage but otherwise link with RSLs.
2. For release builds, copy the spark RSL from the SDK to the deployment directory manually.
