Re: [HAPI-devel] Parser dropping 1 empty repeat on an OBX-5 each time you parse

Thanks for your reply James.

I ran the test you provided, and it passed as you expected.

Couple of things.

The OBX-5 provided in the example has 9 repeats.  You only had code to test 8. If you add the line:

       assertEquals("", obx.getOBX().getObx5_ObservationValue()[8].encode());

Then the test fails.

Alternatively the assertions could be reduced to:

       assertEquals("Count of OBX-5 repeat is 9", 9, obx.getOBX().getObx5_ObservationValueReps());

Which also fails.

To check if this might be something particular to OBX-5 entries, given their variable nature I extended the test to include a check on another repeating field by adding 3 repeat characters to the end of the PID-3 list (making 4 repeats)

               + "PID|1||10011682^^^CL_MRN Pool^^CD:237968946~~~|60683166^^^DONOTSEND^^CD:237968946|CLABTEST^ONE||19500101120000|F||C|34605 W 12 MILE RD^^FARM MILLS^MN^48331-3263^CD:309221^CD:756^^CD:637908|CD:637908|(248)489-6000^CD:170||CD:151|M|CD:3391461|606831661088^^^DONOTSEND^FIN NBR^CD:237968946||||CD:654655774|||0|||CD:654897458\r"

and added another assertion:

       assertEquals("Count of PID-3 repeat is 4", 4, ((ORU_R01) hapiMsg).getPATIENT_RESULT(0).getPATIENT().getPID().getPid3_PatientIdentifierListReps());

This also fails.

Any thoughts on what is going on?

Thanks
Ian

We have been having some trouble with textual OBX-5’s which have repeats used to indicate each line of a report when some empty repeats exist to denote empty lines for formatting.
Is there a way to overcome this?
The following example demonstrates the problem
