Scala - Problem using MapWrapper when upgrading from 2.7.7 to 2.8.1 -


i have piece of code inherited works under scala 2.7.7 (well, replacing import use jcl ). when try use 2.8.1 error:

error: not enough arguments constructor mapwrapper: (underlying: scala.collection.map[string,string])collection.javaconversions.mapwrapper[string,string]. unspecified value parameter underlying.

map.empty ++ new mapwrapper[string, string] {

             ^

i have google high , low, tried different things can't find how modify code work on scala 2.8.1

any pointers great.

thanks

import scala.collection.javaconversions.mapwrapper  object errorobj{   def converttostringmap(javamap: hashtable[string, string]) = {     map.empty ++ new mapwrapper[string, string] {         def underlyinga = javamap     }    } }

mapwrapper class in scala 2.8 (was trait abstract methods in 2.7). so, don’t need define abstract method underlying anymore.

new mapwrapper[string, string](somemap)
