> Comparing an entity to an ObjectId or a Persistent via its "self" property fails when the entity has a compound PK:
> {noformat}
> ObjectId id = ObjectId.of("CompoundPkTestEntity", Map.of("KEY1", "PK1", "KEY2", "PK2"));
> ObjectSelect.query(CompoundPkTestEntity.class)
>               .where(CompoundPkTestEntity.SELF.eqId(id))
>               .selectOne(context);
> {noformat}
>   throws:
> {noformat}
> CayenneRuntimeException: Unable to translate reference on entity with more than one PK.
> {noformat}
>  The same comparison against a *related* entity with a compound PK works fine,  "self" behaves differently from every other entity property:
> {noformat}
> // works
> CompoundFkTestEntity.TO_COMPOUND_PK.eqId(id)
> {noformat}
