When parsing an HL7 2.3 ORM message, with the OBX-2 field set to ID, the
HAPI (0.5.1) implementation throws the error bellow:
[java] Caused by: ca.uhn.hl7v2.HL7Exception:
java.lang.NoSuchMethodException trying to set data type of OBX-5

Reading source code, I found that the Varies implementation attempts to
call a default constructor on the class
ca.uhn.hl7v2.model.v23.datatype.ID :
Class c = factory.getTypeClass(obx2.getValue(),
segment.getMessage().getVersion());
v.setData((Type) c.getConstructor(new
Class[]{Message.class}).newInstance(new Object[]{v.getMessage()}));
Unfortunately, this constructor does not exist. All defined constructors
for the Java type ID expect a table identifier parameter (here it should
be 125).
The issue is that ID _is_ an acceptable value for field OBX-2, as
defined by the HL7 table 125, release 2.3.
And the sending application (Millennium) does use this value.
I could easily patch the HAPI 0.5.1 source code, but I would prefer not
to.
Furthermore, as the spec allow this value, I think this issue may be
reported as an HAPI bug. Should I create an entry in the issue tracker ?
Has anyone encounter a similar issue ? what was then the chosen
solution ?
Regards,
christophe.
