hi,

I receive the following error when trying to use a setPropertySelector class or an excludeProperty() for an Example criteria :

Code:
net.sf.hibernate.PropertyAccessException: exception setting property value with CGLIB (set hibernate.cglib.use_reflection_optimizer=false for more info) getter of ... .dto.FilmTO.?


I've read the HibDocu and forum, but could not make it use. I use JBoss3.2.3 and have only one cglib version, that is located in the ear.

I have Hibernate2.1.2, with the latest cglib version, doesn't help.

What to do now? criteria is a very great tool for my needs, but I have to limit the loaded fields for speed.

looking for your help.

regards,
Thomas

hi micheal,

here's a code snippet from my dao class:

Code:
      try {
         session = getSessions().openSession();
         tx = session.beginTransaction();

         Criteria crit = session.createCriteria(FilmTO.class);
         Example eg = Example.create(FilmTO.class)
            .setPropertySelector(new FilmProps());
            
         crit.add(eg);

         if (criterions!=null) while (criterions.hasNext()) crit.add((Criterion)criterions.next());
         if (orders!=null) while (orders.hasNext()) crit.addOrder((Order)orders.next());

         if (pageSize!=null && pageNumber!=null) {
            crit.setMaxResults(pageSize.shortValue());
            crit.setFirstResult(pageSize.shortValue() * pageNumber.shortValue());
         }
         
         ret = crit.list();
         session.flush();
         tx.commit();
      } catch (HibernateException ex) {


and here's the filter class
Code:
   private class FilmProps implements Example.PropertySelector {
      public boolean include(Object propertyValue, String propertyName, Type type) {
         return !(propertyValue instanceof Collection);
      }
   }



and here the error stack trace:

This is not caused by propertySelector, look at the stackTrace. I suspect you have a primitive type somewhere in your object and have it mapped to a db column which contains null values.

hi micheal,

I've checked all my objects, not just FilmTO, and confirmed myself that all of my private fields stand for objects. I have no primitive field, nor any accessor method with primitive parameter.

Is there any other answer to the error?

hi micheal,

the problem was that Example.create(Object entity) needs an entity Object not a class object. So I changed my code to

Code:
  FilmTO dto = new FilmTO();
  Example eg = Example.create(dto);


But now it returns 0 row. why is that?

I made the Cat example mentioned in the Hibernate Documentation and it also returns zero = 0 lines when adding an Example.create(cat) to the criteria.

why is that? how to receive all the lines?

looking for your help.

regards,
Thomas

Take a look at the generated SQL i'd suggest. I suspect some property is taken into account you are not expecting.

hi micheal,

OK, I've found the error. in my propselector class I had to exclude zero values for Number objects and those null valued objects.

In the cat example, char primitive type property was the problem, exluding it, propertyselector works great.

thanks.

bye,
Thomas
