Problems with Chained Parameters

[danielrehmann]

Hello,
I Currently try to request a MedicationAdministration by a code of its Medication. Therefore i wanted to use a Chained Request (I use a recent version of the Example JPA ).

I made sure there is a correct medication Resource present and that i can properly query it with:
https://localhost:8443/hapi/baseDstu2/Medication?code=04823543

The query with the Chained command is:
https://localhost:8443/hapi/baseDstu2/MedicationAdministration?medication.code=04823543

I now get an Error:

{
  "resourceType": "OperationOutcome",
  "text": {
    "status": "generated",
    "div": "<div xmlns=\"http://www.w3.org/1999/xhtml\"><h1>Operation Outcome</h1><table border=\"0\"><tr><td style=\"font-weight: bold;\">error</td><td>[]</td><td><pre>Failed to call access method</pre></td>\n\t\t\t\t\t\n\t\t\t\t\n\t\t\t</tr>\n\t\t</table>\n\t</div>"
  },
  "issue": [
    {
      "severity": "error",
      "code": "processing",
      "diagnostics": "Failed to call access method"
    }
  ]
}

From the Server I can extract

I think i have a coorect query and hope you can help me with this Problem.

Best Regards,

I also tried this Query on the http://fhirtest.uhn.ca/baseDstu2 server and there I'm also not allowed to query anything below the medication Reference. do you have any idea how this could be solved? I'm working on my Master Thesis right now and need to find Medication Administrations for a specific Medication.

Thank you for your Time,
Daniel

Hi @Crudelus, thanks for reporting!

I believe I have this all solved now. Basically there was a bug where chains didn't work if the parameter pointed to a path that had a choice containing both a resource and a non-resource type (e.g. MedicationAdministration.meditcation[x] is both reference and codeableconcept.

The following search now works: http://fhirtest.uhn.ca/baseDstu2/MedicationAdministration?medication.code=96068333
