[ClassCastException: models.Profile cannot be cast to models.Profile]

This one really puzzles me.

This is my code:

package models

import play.api.Play.current
import java.util.{Date}
import com.novus.salat._
import com.mongodb.casbah.Imports._
import se.radley.plugin.mongodb._
import se.radley.plugin.mongodb.salat._

case class Profile(id: String,
                   displayName: Option[String] = None,
                   public: Boolean = false,
                   nsfw: Boolean = false,
                   created: Date = new Date,
                   meta: Map[String, String] = Map.empty)

object Profiles extends SalatDAO[Profile, String](collection = getCollection("profiles")) {
  def get(id: String): Profile = findOneByID(id).getOrElse {
    val prof = Profile(id)
    insert(prof)
    prof
  }

  def allPublic = find(MongoDBObject("public" -> true))
}

This occurs after an automatic recompiling. If I stop the server entirely, do a clean in the code, then restart, it works - once. After a second re-build, I get this error again.

This is the full exception:

I see that your using the old plugin. Re read the info and update your code accordingly.

I've also encountered this problem, I'm not shure why it's happening. But I'm on it.

I have updated, but unfortunately, the problem persists.

Can you maybe provide me some workaround? Am I using the plugin in a wrong manner?

leon commented

This is fixed in 1.0.2.
The API has changed a bit, so check the README or the https://github.com/leon/play-salat/tree/master/sample to see how to get it started.

I'm seeing this on my current project: "se.radley" %% "play-plugins-salat" % "1.0.9"
Restart play fixes it.
