ScalaReflectException in createCompositeArrayJdbcType

[YanDoroshenko]

Hi, I'm getting a very weird and very long ScalaReflectException in runtime when trying to insert data into DB.

Here's the part that fails:

implicit lazy val cordialFeedVariantArrayTypeMapper: DriverJdbcType[List[CordialFeedVariant]] =
    createCompositeArrayJdbcType[CordialFeedVariant]("CordialFeedVariant").to(_.toList)

The exact point of failure is PgCompositeSupport.scala:71 (typeOf), the message is that class CordialFeedVariant is not found.

Please let me know you need any additional info. Thanks.

I've found a workaround which is to manually create the AdvancedArrayJdbcType constructing and parsing strings manually.

Here's related codes for createCompositeArrayJdbcType,

  def createCompositeArrayJdbcType[T <: Struct](sqlTypeName: String, cl: ClassLoader = getClass.getClassLoader)(implicit ev: u.TypeTag[T], tag: ClassTag[T]) = {
    val util = new PgCompositeSupportUtils(cl, emptyMembersAsNull)
    new AdvancedArrayJdbcType[T](sqlTypeName, util.mkCompositeSeqFromString[T], util.mkStringFromCompositeSeq[T])
  }

Maybe cordialFeedVariantArrayTypeMapper and CordialFeedVariant were loaded by different classloader.

Try createCompositeArrayJdbcType[CordialFeedVariant]("CordialFeedVariant", classOf[CordialFeedVariant].getClassLoader)?
