'Any' type and usage

[Christopher C]

Hello All,

Quick question on the 'Any' usage (in golang). I have some messages defined as below:

message AnyTypeRequest{
  string type = 1;
  google.protobuf.Any req_object = 2;
}

message Type1Msg {

  int32 count =1;

}

message Type2Msg{

  string msg = 1;

}

In the handler I was hoping to switch off the type field to unmarshal the req_object into a proper structure.    The call UnmarshalTo() fails with a mismatched message type because the Any object's TypeUrl is empty.  Do I need to set the Any.TypeUrl to the type I expect it to be, or am I not using this in the proper manner?

Thanks,

Chris
