[HAPI-devel] Does the HAPI Library honor groups when extending MFN_M01?

[Davies, B. <Bri...@Mc...>]

I am extending the MFN_M01 message as this is provided by a 3rd party to an app that I am working on.  I extended the MFN_M01 class for example:
DCS,RXD and MTN extend AbstractGroup and in a package  com.mypackage. sbs.v25.group.  However, none of DCS,RXD or MTN are loaded in the custom model, even though the custom segments are loaded when encountered by the parser.  I adopted HAPI because I wanted to replace the home grown implementation being used but unfortunately encountering numerous issues.  Casting the class to TFM also results in a class cast exception  because the message type/trigger, field 9 is MFN_M01.

public class TFM extends MFN_M01 {
 public TFM(ModelClassFactory theFactory) {
                              super(theFactory);
                              init(theFactory);
               }
private void init(ModelClassFactory factory) {
                      try {
                                                    this.add(DCS.class, true, false);
                                                    this.add(RXD.class, true, true,false);
                                                    this.add(MTN.class, true, true,false);
                                     } catch(HL7Exception e) {
                                                log.error("Unexpected error creating TFM", e);
                      }
  }

Best Regards.
