Hi,

I am also using my own messages, but registering the class doesn't seem 
to work. What am I doing wrong?

I have messages like
nl.portavita.hl7messages.model.v1.message.PVL_PV1
(extends abstractmessage) and message segments like
nl.portavita.hl7messages.model.v1.segment.LGA
(extends AbstractSegment).

In my userdir I have created the directory 'custom_packages' with the 
file '2.2'.
The contents of the file are: 'nl.portavita.hl7messages.model.v1'

calling Parser.packageList results only in {'ca.uhn.hl7v2.model.v22.'}

if I do (in processmessage(Message in))
LGA lga = (LGA)in.get("LGA");
I get a classcastexception. (the 'get-method' returns an 
abstractSegement, and if I inspect it, i can find the complete original 
message somewhere inside)

I have decided to put the messages under '.message', as happens in the 
HAPI, but the JavaDoc has an example with '.messages'. Do I need to 
place all messages under '.messages' instead? Or do I have to place the 
file somewehere else, or do I need to load the file somehow?

Martin
