    Hy guys i want insert a LinkedHashMap into MyObject, with custom date format, and i have use BeanUtils with method populate:

    public Object populate(Object obj, LinkedHashMap<String,Object> hash)
    throws IllegalAccessException, InvocationTargetException {
    Date dateempty=null;
    DateTimeConverter dtConverter = new DateConverter(dateempty);
    dtConverter.setPattern("dd/mm/yyyy");
    ConvertUtils.register(dtConverter, java.util.Date.class);

    A LinkedHashMap should have no trouble with a null value.
    If you tried and it is not working, post the code that shows the problem

    What exceptions are you getting? Always post the full text of any error messages with your code and question.

    I found the solution, if i set DateTimeConverter to null this work:
    Date defaultValue = null;
    DateTimeConverter dtConverter = new DateConverter(defaultValue);
    Thanks!
