我在Erra写一个应用程序，我遇到了麻烦。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，但是当它将带来最好的开发模式时，会抛出代理提供商找到的类型。
还有错误屏幕： BUG FOUNDED IN WEB CONSOLE
我附加了一些屏幕和源代码......

答案 0 :(得分：0)
通过我的IDE（IntelliJ）运行超级开发模式时，我看到了这个错误。当我通过GWT Maven插件（mvn gwt:run -Dgwt.noserver）运行超级开发模式时，此错误消失了。
我不确定导致问题的原因。我的第一个想法是存在版本差异，但IDE和Maven插件都使用相同版本的GWT（2.8.0-beta1）。
希望这有帮助！
