Seems the solution is possible, however a little bit tricky: for some reason you can't import Scala Iterable type into Java code, so everything has to be done in Scala code instead:
*def* createTapestryCoercions(configuration: org.apache.tapestry5.ioc.Configuration[org.apache.tapestry5.ioc.services.CoercionTuple[_, java.lang.Iterable[_]]]) = { *val* coercion = *new* Coercion[Iterable[AnyRef], java.lang.Iterable[_]] () { *def* coerce(arg: Iterable[AnyRef]) = arg.asJava } configuration.add(*new* CoercionTuple(classOf[Iterable[AnyRef]], classOf[java.lang.Iterable[_]], coercion)) } On Sat, Oct 3, 2015 at 12:17 AM, Ilya Obshadko <ilya.obsha...@gmail.com> wrote: > Just checking - did anyone ever try to create general-purpose type coercer > for Scala types? > It seems to be very natural solution to avoid calling .asJava on every > return type I happen to use from Scala. > > > -- > Ilya Obshadko > > -- Ilya Obshadko
