You can see it in CI build [1], and locally by running ant mxtests in royale-asjs root folder.
Line 43 of the flash log [2] shows a stack trace with the following error: Error #1069: Property http://www.adobe.com/2006/flex/mx/internal::setupBindings not found on mx.controls.beads.TitleBarView and there is no default value I suspect it has something to so with the fact that TileBarView is mxml but I have not been able to trace the error to the compiler further than that the exception is being thrown by BindingCodeGenUtils. makeParameterFunction() Any ideas?
