HAPI FHIR R4 : Modifiers on ReferenceParam

I'm currently building a FHIR (R4) Server, and i try to implement the following request:

[base]/PractitionerRole?practitioner.active:not=true

I know that active is a Token Param, and thanks to HAPI, i can use the following command :

TokenParam tokenSubject = referenceParam.toTokenParam(myContext);

But sadly, all the modifier part is lost : in my referenceParam, i only have a chain part (active:not), and a value part (true), so i don't have any modifiers, missing, etc.. So when i convert it to a TokenParam, i don't have neither the modifiers, missing, etc ...

So here is my question : Is there a way to have a ReferenceParam that has modifiers? I would like to have a chain part (active), a modifier (not) and a value (true), as in a real TokenParam

Your syntax looks correct. My best guess is you're using token search directly, instead of as part of a chain.

Token/Identifier alone would be appropriate if you were searching for active directly on PractionerRole.

For example: http://hapi.fhir.org/baseR4/PractitionerRole?active:not=true

However, you're doing a nested search with ?practitioner.active:not=true

Try Search Parameters > 4.5.9 Chained Resource References > Dynamic Chains

For example: http://hapi.fhir.org/baseR4/PractitionerRole?practitioner.active:not=true

NB: active:not=true will return both active:missing and active=false
