Topic: STU3 Validations

While validating some of the STU3 examples I'm getting the below error, are others aware of this one, and
[WARNING] Evaluation of FhirPath for constraint 'rng-2' failed: Invocation of 'binary.or' failed: Invocation of 'binary.<=' failed: Function cannot be called with parameters of type 'collection,collection' (at RiskAssessment.prediction[5].when[0]) [ERROR] Instance failed constraint rng-2 "If present, low SHALL have a lower value than high"(further diagnostics: low.empty() or high.empty() or (low <= high)) (at RiskAssessment.prediction[5].when[0])
And has this been fixed in the post 0.96.0 releases?

Can't say I've ran into it before
Ewout Kramer (May 22 2019 at 08:46):
This is a known issue caused by an error in the specification. STU3 uses a pre-normative version of FhirPath for which comparisons on Quantities have not been defined (hence not implemented in the engines) - yet rng-2 uses this comparison.

That's what I thought. Thanks. Do you know if it is part of the STU3 tech corrections?
Brian Postlethwaite (May 22 2019 at 21:34):
And will the updated fhirpath make this then work? (knowing my build is a little behind)

I hope so, but I haven't followed what's included in the upcoming STU3 corrections.

The FhirPath engine has not been updated yet to normative, so no support for it yet. Partially I am waiting for normative, partially because I need to rewrite the engine, which is something I am taking up after finishing my work on the mapping language.

Cool, thanks Ewout.
