在 GWT 开发模式下运行时出现 com.google.gwt.user.client.rpc.SerializationException
当我们在 GWT 开发模式下运行应用程序时，我们会遇到如下所示的序列化异常，如果我们从开发模式之外运行，则不会出现这些异常。有什么想法吗？请注意，有问题的类 MySDO 扩展自 com.extjs.gxt.ui.client.data.BaseModel，它本身是可序列化的。还有一个公共无参数构造函数
Caused by: com.google.gwt.user.client.rpc.SerializationException: Type 'com.foo.MySDO' was not assignable to 'com.google.gwt.user.client.rpc.IsSerializable' and did not have a custom field serializer.For security purposes, this type will not be serialized.: instance = com.foo.MySDO@fd4410

When we run our application in GWT Dev Mode, we are getting serialization exceptions as shown below that we do not get if we run from outside of dev mode. Any ideas? Please note that the class MySDO in question extends from com.extjs.gxt.ui.client.data.BaseModel which is itself serializable & also has a public no parameter contructor

可能 com.foo.MySDO 包含一些其他不可序列化的类型
May be com.foo.MySDO include some other not serialiseble type
