Scala implicit conversion for Java enums is missing

[Tobias Roeser]

When using QueryDSL 2.2.0 with Scala, Creating queries with expressions on Java enums givens compile errors.

Code example:

override def findByPaymentStatus(paymentStatus: PaymentStatus): JuList[Payment] =
    query.from(payment).where(payment.paymentStatus $eq paymentStatus).list(payment)

Error is (copied from Eclispse IDE):

overloaded method value = with alternatives: (right: com.mysema.query.types.Expression[_$9])
 com.mysema.query.scala.escaped.BooleanExpression <and> (right: _$9)com.mysema.query.scala.escaped.BooleanExpression
 cannot be applied to (de.tototec.tupomoja.request.model.PaymentStatus)

When adding the following implicit conversion in scope, the code compiles fine:

import com.mysema.query.scala.Conversions
implicit def enumPath[E <: Enum[E]](e: E): com.mysema.query.scala.escaped.EnumPath[E] =
    Conversions.aliasFactory.getCurrentAndReset()

I think, this implicit conversion should be added to com.mysema.query.scala.Conversions object.

Thanks for the bug report. Fixed in SVN trunk.
