RE: [HAPI-devel] Peculiar parse of a valid HL7 message in TestPan el

Hi,=20
The structure of each message is defined by a Java class (e.g.
ca.uhn.hl7v2.model.v21.message.*). When HAPI parses a message, it tries =
to
put each segment in the right place in that class structure, but this =
may
not be where you would expect if the segments come in mis-ordered. For
example if a non-repeating segment repeats, HAPI thinks it is the group =
to
which the segment belongs that has repeated. =20
You can make custom message classes to deal with local =
message-structural
curiosities. If you look at a couple of examples of standard classes in =
the
library it should be obvious how to do this. Then you have to register =
your
class with HAPI, as described in the JavaDocs for Parser.packageList() =
and
Parser.findMessageClass().=20

I found that in this particular case, the order of the segments matters.
The DG1 segment was being recognized were is existed in the message, but =
a
placeholder was being put immediately following the PV1 segment where =
hl7api
thought it should be. My next question is where is this structure =
defined
and can it be relaxed as I am receiving messages from another interface =
and
can't control the order of the segments?
Thank you,
Court

When using the HL7 message below, the TestPanel parses the message with =
2
DG1 segments, the first being an empty node and the second containing =
the
actual data. This is curious because a call to terser.get("/DG1-2") and
terser.get("/DG1-4") return nothing with this particular message. I =
have
noticed that is doesn't just happen with the DG1 segments either. I've =
seen
happen with the PV1 segments as well.

Any ideas/leads from an experienced hand?
