Elm Translator: Missing localId for choice type properties

[birick1]

This issue arises from ticket projecttacoma/fqm-execution#290 coming from a MADiE user issue.

For this CQL:

define "Has Medical or Patient Reason for Not Ordering Beta Blocker for LVSD":
  exists ( ["MedicationNotRequested"] NoBetaBlockerOrdered
      with AHA."Heart Failure Outpatient Encounter with History of Moderate or Severe LVSD" ModerateOrSevereLVSDHFOutpatientEncounter
        such that NoBetaBlockerOrdered.authoredOn during ModerateOrSevereLVSDHFOutpatientEncounter.period
      where NoBetaBlockerOrdered.medication in "Beta Blocker Therapy for LVSD"
        and ( NoBetaBlockerOrdered.reasonCode in "Medical Reason"
            or NoBetaBlockerOrdered.reasonCode in "Patient Reason"
        )
  )

With the correct set of patients, we should see “NoBetaBlockerOrdered.medication” highlighted. However, it is not highlighted as seen below:

The root cause for lack of highlighting is that the ELM is missing the localId for the expression. To see this, the generated ELM for this expression is as follows:

With the arrows pointing at the location where a localId should be found.

What’s particularly odd is that a localId for this expression does exist in the annotations:

It is likely a bug that the localId exists in the annotation, but not the ELM expression. If the annotation is added to the ELM as expected:

Then highlighting works as expected (Note: the localId could also be placed in the “code” clause):
