HAPI Chained Parameters Issue

[ndiv...@gmail.com]

Hello,
 

HAPI DSTU3 library returns an error when trying to request a DetectedIssue by a patient identifier using a chained request. 

The query with the Chained command is:
https://localhost:3001/fhir/v1/DetectedIssue?patient.identifier=ABC123ABC

Error returned by hapi library:

Invalid search parameter "patient.identifier".Parameter contains a chain(.identifier) and chains are not supported for this parameter(chaining is allowed only on reference parameters)

As per FHIR  search documentation below is allowed.(https://www.hl7.org/fhir/search.html)

 GET [base]/DiagnosticReport?subject.name=peter

So,

GET [base]/DetectedIssue?patient.identifier=ABC123ABC     should be allowed?

Hi NDivvala,

What version of the library are you seeing this with? And is this with JPA or with your own custom server?

I'm not seeing the same behaviour on our public server, whcih is on the latest 2.5 snapshot ofg HAPI: http://fhirtest.uhn.ca/baseDstu3/DetectedIssue?patient.identifier=ABC123ABC

Cheers,

James

Hi James,

This is on our own custom server leveraging the HAPI JAX-RS Module with RestEasy.

I was using the latest version 2.3 (hapi-fhir-jaxrsserver-base). Even after bumping the version to latest 2.4 the behaviour is same.

Thanks

Ok..

Is your "patient" parameter on the resourceprovider of type ReferenceParam? If not, that would explain this as you can only chain on parameters of type ReferenceParam.

If it is, this might be a HAPI bug. In that case, would you be able to recreate the issue in the unit test ( https://github.com/jamesagnew/hapi-fhir/blob/master/hapi-fhir-jaxrsserver-example/src/test/java/ca/uhn/fhir/jaxrs/server/example/JaxRsPatientProviderDstu3Test.java ) and submit as a PR? That would help to get a fix in.

Cheers,

James

yes, the patient parameter is a reference type.

I will recreate the issue and submit PR,  will reach out if needed any help.

Thanks
