You can configure the date converter with a set of patterns for the
String formats you're expecting and register that, something like:

String[] patterns = new String[] {"yyyy-MM-dd", "dd-MM-yyyy"};
DateTimeConverter converter = new DateTimeConverter();
converter.setPatterns(patterns);
ConvertUtils.register(converter, Date.class);
