Grails controller actions cannot be overloaded

Question

I am trying to use an overloaded method to add XML to a controller in Grails 2.3.4.

I have the following overloaded methods in my ReportController.

String makePhotoXml(StringBuilder sb, Report r, String url, String desc) {

    sb.append("<photo>")
    sb.append(Utilities.makeElementCdata("url", url))
    sb.append(Utilities.makeElementCdata("caseId", r.caseId))
    sb.append(Utilities.makeElementCdata("type", r.type))
    sb.append(Utilities.makeElementCdata("date", r.dateCreated.format('MM/dd/yy')))
    sb.append(Utilities.makeElementCdata("address", r.address))
    sb.append("<extra>extra</extra>")
    sb.append(Utilities.makeElementCdata("description", desc))
    sb.append("</photo>")
}

String makePhotoXml(List<Report> reports) {
    StringBuilder sb = new StringBuilder()
    sb.append("<photos>")
    sb.append("<title>Photos</title>")
    for (Report r : reports) {
        for (Photo photo : r.photos) {
            makePhotoXml(sb, r, photo.url(), photo.description)
        }
        for (Document doc : r.photoDocuments) {
            makePhotoXml(sb, r, doc.url(-1), doc.getDescription())
        }
    }
    sb.append("</photos>")
}

When starting the application, I get this compiler error:

| Error Compilation error: startup failed:
/Users/Anthony/GrailsApps/AppOrderWeb/grails-app/controllers/com/apporder/ReportController.groovy: 1360: Controller actions may not be overloaded.  The [makePhotoXml] action has been overloaded in [com.apporder.ReportController]. @ line 1360, column 5.
       String makePhotoXml(StringBuilder sb, Report r, String url, String desc) {

I thought Groovy and Grails support method overloading. Any ideas on how to get around this and make this overloaded method work?
