Can I ask why you are trying to dynamically change the value of the AM type at runtime via this interface? The traditional way to "change" the AM type is to include multiple instances of SerialAMSenderC() in your configuration, each instantiated with a different AM type. When you want to send a message with a particular AM type, you choose the proper instance of the AMSend interface provided by one of these components.
I'm not sure exactly why what you were trying to do originally wouldn't work in theory, but I suspect it has something to do with not using the proper components in your configuration.
