Topic: Could not resolve onsetDateTime [Condition]
ravi.kuchi (Jun 11 2021 at 02:06):
Hi, I am executing the library as below:
library FMCNAActivityDefinition version '1.0.0'
using FHIR version '4.0.0'
include "FHIRHelpers" version '4.0.0' called FHIRHelpers
codesystem "ICD10": 'http://hl7.org/fhir/sid/icd-10'
code "COLD":
'P80.0' from "ICD10"
context Patient
define "Get Condition from Code Declaration":
[Condition: code = "COLD"]
define "FirstCold":
First([Condition: "COLD"] C sort by onsetDateTime desc)
I am getting the below error:
Could not resolve identifier onsetDateTime in the current library.

Choices in the FHIR model are represented by the root element name, not the type-specific name, so this would be sort by (onset as FHIR.dateTime) desc. The cast is required in this case because the choice has two possibilities that are sortable, DateTime and String, so you have to select which one you want to use.

Note that there is a 4.0.1 model info that is recommended for use with FHIR. Unless you have a specific reason to stay on the 4.0.0 version of FHIR.
