I am using Flex 4.6 and runtime error is thrown in the below line const dimensions:GridDimensions = grid.mx_internal::gridDimensions;
Error Trace: ReferenceError: Error #1069: Property http://www.adobe.com/2006/flex/mx/internal::gridDimensions not found on spark.components.Grid and there is no default value.
