Yeah, tried that. It then complains about trying to convert String to String[]. I do have a BeansWrapper sub-class, but all it does is set these two options:

        setExposeFields(true);
        setSimpleMapWrapper(true);

Not sure how to fix it, but I changed the method to take an Iterable<String> and it is working.
