我想在 iPad 上的 tabris 中激活 UICallback，但是当我UICallback.aktivate("background")在每次显示操作后调用时，会抛出 IllegalArgumentException：

我正在使用 com.eclipsesource.tabris.feature.feature.group 0.7.0.v20120828-1253

我还测试了来自http://developer.eclipsesource.com/tabris/demos/的 Train Dashboard Demo，它出现了同样的问题，但在截屏视频中，它看起来像过去一样工作......

感谢帮助

通过 Testflight 发布了 iOS 客户端的更新以修复该问题（它是由 RAP 中的更改引入的）。火车仪表板演示也针对 Tabris 0.7.0 进行了更新
