Topic: FHIR example validation using ATC coding system?
May Terry (May 18 2019 at 17:49):
Has anyone tried this? If so, can some attach an example or code snippet? I'm working on creating and validating examples for a drug formulary IG and am specifying the ATC coding system (http://www.whocc.no/atc) where the code is at the level of the therapeutic class and not the ingredient. e.g.: "valueCodeableConcept": { "coding": [ {"code": "N02AA", "display": "Barbituates and derivatives"}]}. When I try to validate this through the IG Publisher, I get a null pointer exception. Naturally, if I remove the coding system, the error disappears. I see this uri is supported in HL7 FHIR terminology systems list (https://www.hl7.org/fhir/terminologies-systems.html). Any thoughts or ideas on what to try? Thanks!

Can you post the full null pointer message?
May Terry (May 18 2019 at 19:10):
"Error null validating Coding: java.lang.NullPointerException"
Lloyd McKenzie (May 18 2019 at 19:22):
And the stack trace associated with that?

this is on my todo list, but a full sample would be useful

@Grahame Grieve - see attached. FormularyDrugV1001.json This example has an extension with 2 drug classifications - the first one doesn't include system, the second one includes "system": "http://www.whocc.no/atc". @Lloyd McKenzie - sorry to ask a noob question but where would I find the stack trace output? I usually look at an error log in an output file called qa.html.

If you were building your IG from the command line, what we want is all of the lines that describe the error.
May Terry (May 19 2019 at 00:13):
thanks. Attached is a capture of my command line and subsequent output. usdf_IG_output_20190518.txt also cc'ing @Chris Moesel in case there's any extra logging that I can run to help provide you with more info.
Lloyd McKenzie (May 19 2019 at 00:36):
Thanks. (For your knowledge, there wasn't actually a stack trace in the log
Grahame Grieve (May 20 2019 at 06:52):
so the validation works ok - can you clear the txcache for the IG and try again?
Grahame Grieve (May 20 2019 at 06:52):
if that's still a problem, can you share the source for the IG?
