java - 仅在开发模式下找不到类型的代理提供程序，经典运行是正确的

标签 java gwt errai

我正在 Erra 中编写应用程序，但遇到了麻烦。使用应用程序的 RPC 调用。当我在正常模式下启动时，Vee 运行良好，但当它在开发模式下提供最佳性能时，会抛出找到的类型的代理提供程序。

并且有错误屏幕: BUG FOUNDED IN WEB CONSOLE

我附加了一些屏幕和源代码...

最佳答案

我在通过 IDE (IntelliJ) 运行 super 开发模式时看到此错误。当我通过 GWT Maven 插件 (mvn gwt:run -Dgwt.noserver) 运行 super 开发模式时，此错误消失了。

我不确定是什么原因导致了这个问题。我的第一个想法是存在版本差异，但 IDE 和 Maven Plugin 都使用相同版本的 GWT(2.8.0-beta1)。

希望这有帮助!
