While attempting to serialize this type with gwt-rpc in gwt 2.0: SortedMap<String, List<Custom_Pojo_Object_Interface>>
and a concrete type of TreeMap, I get this error message at runtime: Type 'Pojo_Object_Concrete_Class' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded. For security purposes, this type will not be serialized.: instance = fPojo_Object_Concrete_Class... Both Custom_Pojo_Object_Interface and Pojo_Object_Concrete_Class implement IsSerializable. is this a bug in GWT 2 or am I doing something wrong?
