Regression in Macros?

[Reto Hablützel]

Hi,

I have just moved from 0.11.14 to 0.12.0. Without modifying any code, we now have warnings such as:
/../package.scala:755: Types are not compatible: securesocial.core.providers.MailToken != reactivemongo.bson.BSONObjectID
[warn]   implicit val TokenHandler = Macros.handler[Token]


The case class Token has a field _id of type BSONObjectID - however where is the MailToken coming from? There is no such field in anywhere in the case class itself.

But the Token case class has a companion object that has an apply method that takes a MailToken as parameter -- so I think it is somehow confusing the apply method in the companion object with the "real" constructor in the case class itself.

We have a number of such warnings that all seem to have an apply method in the companion ojbect in common.

As these messages are logged as warnings, it means that's not fatal, but not recommended.

It's generally a good practice not to have different apply for case class, save for migration purposes.
