Thomas Johnson commented on AMQCPP-166:
---------------------------------------

Never mind the Marshall part, I did not see the TextMessage get Marshalled either and it works fine.

>                 URL: https://issues.apache.org/activemq/browse/AMQCPP-166
>             Project: ActiveMQ C++ Client
>          Issue Type: Bug
>          Components: Openwire
>    Affects Versions: 2.1.3
>         Environment: 32-bit XP client with client compiled under VS 2005, ActiveMQ v5.0 is running on a 32-bit Windows 2003 server.

> Modified the vs2005-activemq-example's HelloWorldProducer to use a map message:
> 				MapMessage *message=session->createMapMessage();
> 				message->setInt("MsgNum",ix);
> 				message->setString("Thread",threadIdStr.c_str());
>                 producer->send( message );
> and the HelloWorldConsumer to receive it:
> 			const MapMessage * mapMessage=
> 				dynamic_cast<const MapMessage *>(message);
> 			if (mapMessage!=NULL) {
> 				int num=mapMessage->getInt("MsgNum");
> 				printf("Msg #%d from thread %s\n",num,mapMessage->getString("Thread").c_str());
> 			} else {
> 				printf("Not a map message\n");
> 			}
> The getInt with Msgnum throw a field not in map exception.   After closer inspection, the map was empty.   Also, while not an expert in the code, but I tried tracing it through the producer->send and as far as I could tell, the map was never marshalled.
