Problem of AcEdSSGetFilter::endEntsel() method

I want to use acedEntSel() to let user to select a special type entity.

So I use the AcEdSSGetFilter reactor as follow

void AcEdSSGetFilter::endEntsel(Acad::PromptStatus returnStatus, const AcDbObjectId& pickedEntity, const AcGePoint3d& pickedPoint, AcEdSelectionSetService& service) { service.remove(0); //comment this line will always return eNormal returnStatus = Acad::PromptStatus::eRejected; }

I want to prompts the user to select an entity again when he selects a wrong type (like the arxdoc said). But I can't distinguish whether the user cancel the acedEntSel() method or select a wrong type.

If I use service.remove(0) the acedEntSel() always return eError (same result with user cancel). It seems I can't change returnStatus success since it don't have a "&" flag.

What can I do to achieve my purpose?
