Topic: Can't cast to Money

I'm having the same issue in https://github.com/HL7/fhir/pull/335 and https://github.com/HL7/fhir/pull/334 - I can't move a money element around, it fails on casting:

org.hl7.fhir.exceptions.FHIRException: Unable to convert a org.hl7.fhir.r4.elementmodel.Element to an Money
    at org.hl7.fhir.r4.model.Base.castToMoney(Base.java:508)
    at org.hl7.fhir.r4.model.ExplanationOfBenefit$TotalComponent.setProperty(ExplanationOfBenefit.java:10501)
    at org.hl7.fhir.r4.utils.StructureMapUtilities.processTarget(StructureMapUtilities.java:1809)

I've looked into it, Base.java public Money castToMoney(Base b) is failing and doesn't think b is an instanceOf Money even though b.toString() says totalCost=Money[3 children]

Given that Money was reworked I'm guessing this is the sideeffect

hmm. I'll have a look at it

OK let me know. I have a couple of maps that are stuck on this

Grahame Grieve (Dec 04 2018 at 18:41):

ok:

group ExplanationOfBenefitTotalCost(source src, target tgt) extends BackboneElement {
  // src.category -> tgt.category;
  src as vs -> tgt.amount as vt then Money(vs, vt);
}
