Should the Dartium version being doing a conversion also?  Or is it already
doing it in C++?

[blois, 2013/07/10 20:10:46]

Dartium is already doing it (tests pass on Dartium), generated code for the
constructor is:

  ScriptValue detailArg =
DartUtilities::dartToScriptValue(Dart_GetNativeArgument(args, 4), exception);
  if (exception)
      goto fail;

  receiver->initCustomEvent(typeArg, canBubbleArg, cancelableArg, detailArg);

Also the getter for detail does a similar conversion.

 
     return e;
