Thanks so much for the override.
It solved the 'getAnimation' error, but animations are not consistent.
- Chrome and Safari (desktop and iPhone simulator): Animations goes from right to left only.
- iOS 5 Simulator with phonegap: works correctly.
- Android with phonegap: the app doesn't even launch with PR2, but that should be another issue.
Indeed there is much work to do on Animations and this will be done before a final release. We do feel that those problems have a lower priority to other issues such as missing functionality or critical bugs such as this one.
