Binding null value enums

In play.data.binding.Binder you have such code beginning at line 78:

            // Enums
            if (Enum.class.isAssignableFrom(clazz)) {
                if (value == null || value.length == 0) {
                    return MISSING;
                }
                return Enum.valueOf(clazz, value[0]);
            }

It works fine until one wants to pass null value for enum from html form. In that situation value[0] would contain empty string which causes "No enum const " exception. This in turn causes #{ifErrors} tag to return true.
