Hi,
I'm confused about some scala, which isn't behaving as expected
My code is:
override def postcodesForSector(sector: PostalSector) = {
// getEm.flatMap(_.createNamedQuery[Postcode]
("findPostcodesForSector", ("sector" -> sector + "%")))
val likeString = sector.name + "%"
//val query = getEm.createNamedQuery[Postcode]
("findPostcodesForSector", "sector" -> likeString)
//query.findAll
getEm.findAll[Postcode]("findPostcodesForSector", "sector" ->
likeString)
}
getEm returns a ScalaEntityManager
the override is overriding the trait method declaration
def postcodesForSector(sector: PostalSector) : List[Postcode]
But I'm getting a compiler error
C:\programmingExperiments\scala\domains\JPADemo\src\main\scala\uk\co
\optrak\infrastructure\repository\addresses\uk
\PostcodeRepositoryImpl.scala:28: error: type mismatch;
[WARNING] found : java.lang.Object with
scala.collection.jcl.BufferWrapper
[uk.co.optrak.scdomain.addresses.uk.Postcode]
[WARNING] required: List[uk.co.optrak.scdomain.addresses.uk.Postcode]
I'm using scalajpa 1.1 which says that the findAll method should
return List[A] not ..BufferWrapper[A]
Any suggestions
Thanks
Tim
