Hi, I have a simple entity: Ent(val id: Long?) : Persistable<Long?>.
This of course requires to implement getId and isNew.
But when I try to implement getId I have Platform declaration clash error;
if I don't implement it, I have Class Ent must be declared abstract or implement abstract method error.
What's the correct way to do this?

czar: what about using secondary constructor?

[ugurk]

@Czar and another workaround can be backing that field

[Czar]

@ugurk I don't see how that helps, can you provide an example using my Ent class?

[ugurk]

making that variable private solves it

[ugurk]

class Ent(private val id: Long) : Persistable<Long?>

[ugurk]

this should work, compiled and run successfully

[Czar]

It does, thank you! Looks like a hack, but not too ugly and it works, so I'm happy (for now) 🙂

Btw this compiles fine in 1.1.3

class Ent(val id:Long) : Persistable<Long> {
  override fun isNew(): Boolean {
    return false
  }

  override fun getId(): Long {
    return this.id
  }
}

@strelok, of course it does, but an Entity id must be Long? not Long and that does not compile.
