I can't seem to figure out how to combine JpaSpecificationExecutor with Keyset scrolling (hence Window return type). It shows me errors of this kind:

At least 1 parameter(s) provided but only 0 parameter(s) present in query

I'm trying to use it like these:

@Repository
interface UserRepository : JpaRepository<User, Int>, JpaSpecificationExecutor< User > {
...
    fun findBy(spec: Specification<User>, limit: Limit, position: ScrollPosition): Window<User>

I call it like this:

val spec: Specification<User> = Specification { root, query, criteriaBuilder ->
    criteriaBuilder.equal(root.get<String>("name"), "John")
}

val position = ScrollPosition.keyset()
val limit = Limit.of(10)

val rows = userRepository.findBy(spec, position, limit)

It fails on the last line, when calling findBy.

I also tried to tweak it in various ways, tried TypedQuery and KeysetScrollSpecification for customizing the query, and it all gives the same errors.

Any ideas how to make it work? It seems all the specification / criteria API is only compatible with offset based paging? What would be my options for building more complex queries with keyset scrolling?
