It looks like there is an issue with the latest AIR version, after they updated the geometry APIs.
I am trying to run some projects and i get the following errors: param count mismatch virt params=2 optional=1 flash.geom::Transform/getRelativeMatrix3D() over params=1 optional=0 flash.geom::Transform/getRelativeMatrix3D() VerifyError: Error #1053: Illegal override of Transform in mx.geom.Transform. at spark.primitives.supportClasses::GraphicElement/validateProperties()[D:\flex_sdk\Sources\flex-sdk\frameworks\projects\spark\src\spark\primitives\supportClasses\GraphicElement.as:3546] at spark.components::Group/validateProperties()[D:\flex_sdk\Sources\flex-sdk\frameworks\projects\spark\src\spark\components\Group.as:938] at mx.managers::LayoutManager/validateProperties()[D:\flex_sdk\Sources\flex-sdk\frameworks\projects\framework\src\mx\managers\LayoutManager.as:601] at mx.managers::LayoutManager/doPhasedInstantiation()[D:\flex_sdk\Sources\flex-sdk\frameworks\projects\framework\src\mx\managers\LayoutManager.as:787] at mx.managers::LayoutManager/doPhasedInstantiationCallback()[D:\flex_sdk\Sources\flex-sdk\frameworks\projects\framework\src\mx\managers\LayoutManager.as:1191] Any ideas? -- Sent from: http://apache-flex-users.2333346.n4.nabble.com/
