Controlled vocabularies not working

[mardo]

I have followed the steps here:
http://longevityframework.org/manual/poly/cv.html

My Model looks like this:

@polyComponent[DomainModel]
sealed trait TicketType

@derivedComponent[DomainModel, TicketType]
case object Congratulation extends TicketType

@derivedComponent[DomainModel, TicketType]
case object Observation extends TicketType

@persistent[DomainModel]
case class User(
  username: Username,
  email: Email,
  fullName: FullName,
  ticketType: TicketType
)

When trying to persist a user, I am presented with the following error:

Good catch! My existing test for this (https://github.com/longevityframework/longevity/tree/master/longevity/src/test/scala/longevity/integration/model/controlledVocab) didn't catch the bug because the problem only comes up when all the deriveds are case objects. In my test case, one of the deriveds was a case class.

I have a fix locally, it will take a bit to go through the rigamarole of creating a bugfix release..

@sullivan- One thing to note is that while adding a case class as a derived component, it will compile, but it still won't work if you try to persist an instance with a case object. Not sure if you already noted that, but just making sure.

@mardo can you please try with version 0.25.1 and let me know if it fixes the problem? Thanks

[mardo]

It works, @sullivan-! Thanks a lot!
