[HAPI-devel] Message Casting Error

[Matias K. <ma...@et...>]

Hello,

I've just started testing HAPI v0.4.1.  I'm trying to cast a Message
object to an ADT_A04 object.  Here is my code:

public ADT_A04 convertMessage(Message in){
	ADT_A04 adt = (ADT_A04) in;
	return adt;
}

When I pass an ADT_A04 message to this function, I get the following error:

java.lang.ClassCastException
         at com.test.HL7.processors.ADTProcessor.processMes
age(ADTProcessor.java:67)
         at 
ca.uhn.hl7v2.app.MessageTypeRouter.processMessage(MessageTypeRouter.
ava:52)
         at ca.uhn.hl7v2.app.Responder.processMessage(Responder.java:159)
         at ca.uhn.hl7v2.app.Receiver$Grunt.run(Receiver.java:115)

What would cause this considering that the message being passed in is an 
ADT_A04 message?  Could this be a versioning problem (i.e. the message 
is v2.4 and the ADT_A04 class is from the v2.3.1 model package)?

Thanks,

Matias
