FHIRPath precedence operators of in and or not honored

[oliveregger]

The following FHIRPath expression gives an error in IG Publisher:

original: status in ('registered'|'cancelled') or value.exists() or hasMember.exists() or component.exists() or dataAbsentReason.exists()

HAPI-0389: Failed to call access method: org.hl7.fhir.exceptions.PathEngineException: Unable to evaluate as a boolean: registered,cancelled (@char 11)

according to operator precedence in should be before or and ('registered'|'cancelled') should not be evaulated to boolean.

making it explicit (status in ('registered'|'cancelled')) or value.exists() or hasMember.exists() or component.exists() or dataAbsentReason.exists()

it returns no errors.

javascript.js. Java (IBM) and the .NET (Firely) implementation are working with the original as expected in FHIRpath Lab:
