Topic: fhir.parser.DataFormatException when searching for o

For Fhir 2.2, DSTU2
We have a named query returning a bundle of Patient and WalkInQueueItems. WalkInQueueItem is our own FHIR domain resources, and not a dstu2-ressource (surprise...).
In end-2-end test we test this by calling:
FhirContext ctx = FhirContext.forDstu2();
ctx.setParserErrorHandler(new NoLoggingErrorHandler());
client = ctx.newRestfulGenericClient("http://" + getUrl());
client.search()
.byUrl("Patient?_query=activeQueueItems")
.where(<someClientParam))
.returnBundle(ca.uhn.fhir.model.dstu2.resource.Bundle.class)
.execute();
(we are not happy about the byUrl-part, would have loved a "withQuery(String)"-possibility)
This results in the following error:
Caused by: ca.uhn.fhir.parser.DataFormatException: DataFormatException at [[row,col {unknown-source}]: [1,893]]: Unknown resource name "WalkInQueueItem" (this name is not known in FHIR version "DSTU2")

I have tried with a extension of a DSTU2-ressource(location) in stead of WalkInQueueItem: same error
I have tried with a standard DSTU2-ressource (appointment) in stead of WalkInQueueItem: no error
Seems to be a bug? Any workarounds?

Most of the samples on http://hapifhir.io/doc_extensions.html assumes that the extended resource is defined as a class that is registered in the context using annotations. Is your server exposed somewhere?
Allan Bro Hansen (Jan 18 2017 at 09:40):
We extend the dstu2 hapi classes.
E.g extending Location:
@ResourceDef(name = "ArrivalLocation")
public class FhirArrivalLocation extends Location
Eg. extending baseResource:
@ResourceDef(name = "WalkInQueueItem")
public class FhirWalkInQueueItem extends BaseResource

@James Agnew : any input on this?

Hi
I needed to register the ressources:
ctx.registerCustomTypes(Arrays.asList(FhirWalkInQueueItem.class));
and it works :-)

Great ;)
